Though it was created with guitarists in mind, the concepts explored can be applied to a variety of musical instruments. CHORDMASTER is designed to be an educational aid and reference, useful for a variety of educational and compositional purposes. CHORDMASTER UNREGISTERED VERSION 1.6 FEATURES - NEW!!! - Support for Sound Blaster and other sound cards. Interactive Chord Entry Table for easy input of chord entries. Chord entries can quickly be transposed to different keys. Chord libraries files for over 50 different chords. Enhances fretboard visualization by showing all notes of a chord on the fretboard. Fretboard views can be shifted to show a specific area. Two fretboards can be viewed simultaneously. Chords can be played by a MIDI device or internal speaker. Notes for two chords can be overlayed on one fretboard, allowing analysis of similarities and differences. Chords can be viewed either as notes or scale sequences. Chords can be input by name or by specifying notes to be resolved to a known chording. Obscure inputs can be resolved to proper chords, i.e. Amaj add7 = Amaj7, A C# E G# = Amaj7. Chords can be resolved to up to five chord synonyms. Individual chord display can be limited to certain string and fret ranges. Context-sensitive HELP screens. Mouse and printer support. - 1 - *** INSTALLATION CHORDMASTER requires about 250 Kbytes of disk space, and can be run from either a floppy or hard disk. Versions distibuted on floppy disk can be run as is by logging the floppy drive and executing the program. Example: A: (logs the drive) CHORDS (executes the program) A floppy disk version can easily be installed onto another disk or hard drive by copying the CHORDMASTER files and directories to the desired drive. Example: C: (logs the drive) CD\ (start from root directory) MD CHORDS (create chord directory) CD CHORDS (log the chord directory) COPY A:\*.* (copy CHORDMASTER from floppy) CHORDS (executes the program) Shareware versions of CHORDMASTER are distributed in ZIP format and require PKUNZIP to install. Here's a sample hard drive installation that assumes that the CHORDS16.ZIP file is in the current directory. Example: MD \CHORDS (create chord directory) PKUNZIP CHORDS16 \CHORDS (unzip CHORDMASTER) CD \CHORDS (log the chord directory) CHORDS (executes the program) WINDOWS USERS - CHORDMASTER will run either full screen or windowed in WINDOWS 3.x. A windows icon (CHORDS.ICO) is included. Create a PIF file for CHORDMASTER using the PIF editor. 128K of RAM is required. To run CHORDMASTER in its own window, WINDOWS must be started in 386 enhanced mode. If using the enhanced mode add a 'w' in the Optional Parameters box of the PIF screen. This will disable CHORDMASTER's graphical startup screen and avoid a video error in WINDOWS. NOTE : Mouse functions will not work if CHORDMASTER is executed in window. Sound Card functions may not work in WINDOWS. - 2 - *** CHORD ENTRY After the opening screens the program will display a blank fretboard and the cursor will blink, prompting for a chord entry. There are several ways to enter chords. CHORD ENTRY METHODS Chord Entry Table - A quick interactive method for chord entry. Command Line - Type in the name of a chord. Note Entry - Specify the notes in a chord and let CHORDMASTER identify it. Each of these methods is discussed below: CHORD ENTRY TABLE CHORDMASTER's Chord Entry Table is a quick, convenient way to enter a chord to be displayed. The table can be accessed by striking the F10 key to access the OPTIONS menu, and selecting the appropriate option from the DISPLAY submenu. MOUSE USERS : The Chord Entry Table can be accessed by clicking at the top of the screen when CHORDMASTER is expecting a chord entry. The Chord Entry Table consists of four component sections: KEY, SUFFIX, ADD, and ALTER. The first and second sections, KEY and SUFFIX, are essential and one item from each is always selected. The ADD and ALTER sections are not essential and selections in them are optional. MAKING SELECTIONS TAB to move from section to section. ARROW keys to move around within a section. SPACE BAR selects/deselects the highlighted item in the ADD/ALTER section. MOUSE USERS : Click on an item to select it, click again to deselect. Note that at any given time certain ADD/ALTER selections are darkened and not available. Which selections are available will depend on which SUFFIX and other ADD/ALTER selections are made. The Chord Entry Table reacts interactively, showing which combinations are musically permissible. - 3 - *** CHORD ENTRY TABLE - OPTIONS FREE ARROW KEYS - Some keyboard users will find this option a more convenient way to traverse the table. Using this method the ARROW keys can traverse the table, moving from section to section. The TAB key need only be used to anchor selections in the leftmost columns of the KEY or SUFFIX areas. This method requires fewer keystrokes to accomplish many of the same tasks. REMEMBER LAST CHORD - This option makes the Chord Entry Table remember the previous chording that was entered with the table. This is useful when entering successive chords that are similar in some respect. COMMAND LINE CHORD ENTRY Use the following format for entering a chord by name: [A-G][#,b(optional)] [chord identifier options] At the very least you must enter an uppercase letter in the range of 'A' through 'G'. Optionally, you may indicate that the note is to be sharped or flatted by adding a '#' for a sharp or a lowercase 'b' for a flat. Why the preoccupation with upper and lowercase? Consider a B flat chord. It looks fine as 'Bb', but kind of silly as 'bb', 'BB', or 'bB'. So you must enter the key or root of the chord you want to work with. If this is all you enter it is assumed that you are looking for a major chord. To specify other chords you must add one or more chord identifier options, separated by spaces. The following are legitimate identifier options: FIRST GROUP maj maj6 maj7 maj9 maj11 maj13 minmaj7 minmaj9 min min6 min7 min9 min11 min13 dim dim7 5 6 7 9 11 13 aug aug9 aug11 noroot SECOND GROUP add or / sus + or - (followed by numbers 2 - 13) - 4 - *** Identifiers may be combined, separated by a space, in any combination that is musically sensible. Now, what is musically sensible may vary according to whose rules you are following. For the most part you will use one of the identifier options in the first group, optionally followed by one or more of the identifier combinations in the second group. The identifiers in the first group are common in describing chords. See a book on chord theory for an explanation of these identifiers. The identifiers in the second group are less common and are often written in different ways. Here is brief explanation of the second group: add or / - Used to add a tone to tone to a chord. These are useful in creating common and exotic chords and scales. The catch is that the tone to be added must not have been described in a previous identifier or an error message will result. sus - Generally used to add a 2nd or 4th tone to a chord at the expense of the 3rd. + or - - used to add an altered tone, or alter an existing tone, to an existing chord. Here are some of the errors that can be encountered during chord entry. Errors only occur when using the command-line input method. ILLEGAL - What you typed is nonsensible. STEP ALREADY EXISTS - Your trying to add (add or /) a tone that has already been established. TONE SPECIFIED IS > 13 - You've tried to add or alter a tone that is greater than 13. ILLEGAL TONE SPECIFIED - You've tried add or alter a non-numeric entity. NOTE ENTRY Entry can also be accomplished by specifying the notes to be used in the chord. CHORDMASTER then attempts to identify the chord. Note entry is particularly easy with a mouse. Non-mouse users should use the RESOLVE - NOTE ENTRY item in the OPTIONS menu (pg. 13). IMPORTANT : A chord entered by notes cannot be properly identified unless all notes in it's formula are part of the entry. NOTE ENTRY with a mouse: Enter a chord's notes by clicking on the desired fret positions on the active fretboard. Clicking on a previously selected note will de-select it. Once the desired notes have been selected, click on the word PROCESS which will appear above the active fretboard. If the notes can be identified as a chord, its name will be displayed. The lowest note selected will be considered as the primary root for the resulting chord. - 5 - *** Once a valid chord has been entered, all the notes in the chord are displayed on a fretboard and the notes are sounded through the system speaker. Additionally, a display appears above and to the right of the fretboard showing the relationship of the notes in the chord to the tones in a scale. This display is the chord formula header. For instance, if 'A' is entered; the chord formula header will display the following: 1 2 3 4 5 6 7 A C# E This indicates that the 'A' major chord that was entered has three tones in it; a 1st or root, a 3rd and a 5th. Therefore, an 'A' major chord has a formula of 1, 3, 5 . The established spacing of these notes is function of established music theory and will not be discussed in this section. It is not necessary to fully understand these mechanisms to begin using and enjoying CHORDMASTER. An additional line of text appears immediately below the fretboard, this is called the RESOLVE line. If you entered 'A', as in the example above, this line would simply read 'A MAJ'. This may seem kind of redundant at this point, but as you will see as you read on, the RESOLVE line is one of CHORDMASTER's most powerful features. Let's look again at the fretboard. If you have entered the simple example chord shown above, the fretboard shows all the notes in an 'A' major chord scattered about the fretboard. This is a powerful visual tool. It allows the user to visualize an entire section of fretboard. In this case, any fingerable combination of notes that contains at least one 'A', one 'C#' and one 'E', is a legitimate 'A' major chord. Don't worry, CHORDMASTER can also display individual chord fingerings as we will see shortly. - 6 - *** SCREEN COMMANDS If you have been following along, a word should appear in the center of the screen. This is actually one of a series of possible choices called the AUTOMENU. If you strike the SPACEBAR repeatedly, alternate selections will appear. A selection is executed by striking ENTER. Let's take a look at each of these selections: REENTER - This selection only appears if there was an error in the most recent chord entry. OVERLAY - Allows entry of another chord, whose notes will appear in combination with those already on the active fretboard. On a color monitor, the results may be particularly revealing. SWITCH - Opens a fretboard on the opposite half of the the display for chord entry. CLEAR - Clears the active fretboard for chord entry. OPTIONS - Displays the OPTIONS menu. QUIT - Exits the program. The OVERLAY and SWITCH functions provide added power in fretboard visualization; allowing the user to view various chord patterns together, or side by side. MOUSE USERS : To cycle through AUTOMENU choices, position the cursor in the center of the screen and click the right mouse button. Click the left mouse button on the desired selection to execute it. Chord entries equivalent to the OVERLAY, SWITCH, CLEAR and REENTER can be initiated by clicking the left mouse button over the desired input area. The OPTIONS menu can be accessed by clicking the left mouse button at the top of the screen. - 7 - *** FRETBOARD COMMANDS There are several quick key combinations available after a chord is entered, they are: <- or -> - Shifts the fretboard view range left or right. At any one time 16 frets are visible, over a range of 25. P - Repeats the playing of the tones in the chord. - or + - Changes the timing of the playing of the tones in the chord. D - Displays individual fingerings for the entered chord. UP or DOWN arrows - TRANSPOSE the most recent entry to a higher or lower key. T - Switch between like keys. For example 'C#' to 'Db'. F10 - Accesses the OPTIONS menu. MOUSE USERS : The OPTIONS menu can be accessed by clicking the left mouse button at the top of the screen. DISPLAY of individual chordings can be initiated by clicking on the DISPLAY box which will appear above the active fretboard. Entries can be TRANSPOSED thru keys by clicking on the appropriate side of the TRANSPOSE button. Clicking in the middle of the button will switch between like keys. For example 'C#' to 'Db'. - 8 - *** DISPLAYING CHORDS Once a valid chord is entered on fretboard, individual chordings can be displayed. This can be accomplished by pressing a 'D' on the keyboard or selecting DISPLAY from the OPTIONS menu. During DISPLAY the following keys are active: <- and -> previous and next chords + and - to change play timing P repeat chord play ESC to quit DISPLAY MOUSE USERS : If mouse hardware is detected, buttons for some of the functions listed above will appear above the active fretboard. Simply click on the desired button to display chords. Use basic chord entries to test the DISPLAY system. If all attempts to DISPLAY result in file errors it is likely that CHORDMASTER is improperly installed. Be sure that the chord files (.CDF) in the CHORDS directory. This is an unregistered version of CHORDMASTER and it comes with fewer chord library files than the registered version. If you purchase the registered version you will receive the full chord library which will display tens of thousands of different chords, as well as an integrated chord librarian and editor. This allows the user to add new chords and create custom chord libraries. DISPLAY LIMITS Limits may be placed on the selection of chords to be displayed. This is accomplished using the DISPLAY SETUP menu option, which is described in the next section of this manual. If any limits have been placed on the chords selected for display, a message will appear advising the user that not all chords are being displayed. - 9 - *** OPTIONS MENU Let's examine the various features in the options menu. We will work through the drop-down menus left to right. DISPLAY MENU The DISPLAY drop-down menu consists of three items. The first choice, DISPLAY is equivalent to pressing the 'D' key after chord entry. This choice initiates DISPLAY of individual chordings within the parameters specified by the second choice, DISPLAY SETUP. DISPLAY SETUP This menu selection brings up the DISPLAY SETUP menu. The DISPLAY SETUP menu allows the user to specify the fret range, strings, and number of notes allowed for the chords to be displayed. Move from from field to field by pressing the up or down arrow keys, TAB or ENTER. When the setup is as desired press F7 to save. Press ESC to exit and ignore changes. For each STRING use the SPACEBAR to indicate whether it should be used for DISPLAY. If too many strings are disabled an error message will appear. The number of strings required will vary according to the formula of the most recently entered chord. Specify the fret range over which chords should be displayed by adjusting the LOW FRET and HIGH FRET entries. Remember, not more than 16 frets can be diplayed at one time. However, individual chordings may be displayed over a smaller range of frets. Select the MINIMUM and MAXIMUM number of notes in chords to be displayed. The MAXIMUM number of notes depends on how many strings are used, the MINIMUM limit is determined by the formula of the chord. Select which tone in the chord should be the BASS NOTE. Most commonly '1' would be entered to select the root note as the bass. However, more chords will be displayed if '0' is entered, indicating no preference. The NOTE BLINK selection toggles the blinking of notes in a chord as they are displayed. MOUSE USERS : Click on a field to move cursor, click on a command to execute it. INTERVALS This menu selection offers a choice between displaying notes on the fretboard by their musical names (i.e. A, F#, D, etc.), or by the number of the scale step that they represent in the selected chord. - 10 - *** TUNINGS MENU The TUNINGS menu allows fretboards to be tuned in a variety of manners. Tuning changes affect subsequent chord entries on. Menu items allow for a quick change to STANDARD, OPEN A, OPEN C, OPEN D, OPEN E or OPEN G tunings. The final menu item provides for CUSTOM TUNING, in which any string can be altered from the standard tuning up to four half steps in either direction. NOTE : Individual chord DISPLAY is only available for standard tuning. PLAY MENU This menu consists of two ON/OFF selections . . . PLAY ON ENTRY - Chord play on entry PLAY ON DISPLAY - Chord play on DISPLAY . . . and the PLAY SETTINGS menu. PLAY SETTINGS The PLAY SETTINGS sub-menu provides selections that control the ATTACK and DURATION timings of the chords being played. Units of time are defined as system ticks; approximately eighteen per second. Chords can be played through a MIDI device and/or Sound Card, by enabling these via the appropriate Check Boxes. If either of these devices exist, additional menus will be available. Press 'F2' for MIDI settings or 'F3' to set instruments for a Sound Card. MIDI SETTINGS PATCH DATA - Set the desired patch number to be transmitted to the MIDI device prior to playing. Use numbers '1 -128' for patch data, or '0' to indicate that no patch data will be sent. KEY VELOCITY - Set the MIDI key velocity as desired. The default is 48. LOWEST MIDI CHAN - While the MIDI specification describes numbers '0 - 15' for MIDI channel numbers, most devices use numbers '1 - 16'. Specify the desired scheme here. The default is '1'. MIDI CHANNEL - Specify which channel MIDI data should be sent on. Use numbers '0 - 15' or '1 - 16' depending on the setting of the LOWEST MIDI CHANNEL selection. - 11 - *** SOUND CARD INSTRUMENTS Use this selection menu to tryout and/or select different instrument sounds when using a Sound Card. The selection list appears with the currently selected instrument hi-lited. If a new instrument can be tested by selecting it from the list and using 'T' to play a test chord. NOTE : Sound Card output must have been enabled in the previous menu for a chord to be played. Once the desired selection has been made, it may be locked for future sessions by using the SAVE CONFIGURATION option under the FILES menu. FILES MENU SAVE CONFIGURATION The selection saves information about current program settings in a file called CHORD.CFG. The settings saved in this file are restored every time the program is started. FACTORY SETTINGS Restores program settings to the original settings distributed with the program. PRINT MENU This drop-down menu consists of several selections which initiate printing of fretboards. Printed output is sent to the standard print device. - 12 - *** RESOLVE MENU The RESOLVE drop-down menu consists of selections that control the way chordings are resolved and displayed. RESOLVE performs two important functions. First, RESOLVE can take an awkward chord entry and show a more eloquent method of achieving the same result. For instance, if you entered 'A MIN /2 /7', RESOLVE would "correct" your entry by responding with 'A MIN9'. This is a useful educational tool, helping to reinforce the user's understanding of chord chemistry. Secondly, RESOLVE's perform is critical to the DISPLAY of individual chordings. This is very important, so it should be emphasized that DISPLAY WILL NOT BE AVAILABLE FOR A CHORD UNLESS IT IS RESOLVED TO A CHORD WITH A ROOT, AND A CHORD FILE EXISTS FOR AT LEAST ONE RESOLUTION. RESOLVE is capable of revealing chord synonyms. Factory settings limit the RESOLVE line display to three resolutions, but by altering these settings up to five synonyms or near matches can be displayed. These synonyms may or may not include NOROOT chords depending on the settings. This has implications in DISPLAY mode; if a chord is resolved to more than one perfect match by RESOLVE, chord library files for both chords would be combined and the resulting chordings DISPLAYed. While this increase in DISPLAYed chordings is usually modest, it does provide a means by which NOROOT chords can be DISPLAYed, despite the fact that no chord library files exist for them. To see this mechanism in action use the RESOLVE dropdown menu to set RESOLVE as follows DISPLAY ON, SET COUNT=2, PERFECT ONLY ON and NO ROOT OFF. Obtain a clear fretboard for entry and enter 'A MIN6'. The RESOLVE line now indicates 'A MIN6 F#MIN7 -5'. Upon DISPLAY files for both chords will be opened and combined for more chordings. Here's a description of the RESOLVE menu functions: RESOLVE - Resolves the most recently entered chord according to the current RESOLVE settings. DISPLAY - Enables or disables the display of the resolve line. Either way RESOLVE still occurs and the results affect DISPLAY. SET COUNT - Sets the number of resolutions RESOLVE will attempt to achieve. PERFECT ONLY - This setting decides whether or not non-perfect chord synonyms will be resolved. On the resolve line perfect synonyms are shown in reverse video. NO ROOT - This setting decides whether NOROOT chords will be resolved. - 13 - *** NOTE ENTRY - Provides a means by which individual notes of an unknown chord can be entered and then resolved to a known chord. Notes should be entered separated by a space. Note Entry can be more easily accomplished using a mouse (pg. 5). The first note entered will be considered as the primary root note for the chord. - 13 -
