Add Custom Tunings

If your favorite tunings are missing from the ChordLocator menus, use the form below to define up to 3 custom tunings. You can also use the form to edit or remove any of your custom tunings. Your tunings will appear at the top of the ChordLocator tuning menus, labeled 'Custom'.

Instructions

Enter the tuning name as you would like it to appear in the tuning menus. Then enter the notes, starting with the top string using midi numbers [31 thru 72] or scientific notation [G1 thru C5]. This is necessary because some tunings—those with chromatic notes, for example—have pitches that are not in strict descending order making it difficult for the script to guess the exact pitches if only simple note names are given. Refer to the keyboard diagram below for help or view a listing of popular tunings with correctly defined pitches or a complete table of notes correctly spelled in midi and scientific notation.

Enter the primary key associated with your tuning's open notes into the Key Center field (C F#, Bb, etc.). You are not required to do so but it helps the locators correctly spell chords and scales in your custom tuning and helps correctly name the scale forms.

To delete any or all of your tunings, just clear information from the form below and click the Save Settings button. You must clear the tuning name, tuning notes, and key center entry for each custom tuning you want to delete.

Tuning Restrictions

You can enter up to 12 notes per tuning. Be advised that the script may break if you enter a 12-string tuning with small intervals between notes.

Sample Tuning Definitions

To define custom tunings you must enter specific notes in the form above. You do this by writing the notes in Scientific Notation or using Midi Numbers. The following examples show normal tunings expressed informally as letters, and how you would express them as specific pitches using either method.
