Clicking on the 'Extra information' page button and the the 'Chord symbols' page button will open the Chords pop-up page (only available for OpenSong songs, not PDF files, etc).
This feature allows you to see how to play chords in your song. Currently you can choose from guitar, ukulele, mandolin, banjo (4), banjo (5) and cavaquinho chords. The app comes built in with the most commonly used chords (major, maj7, 7th, 6th, sus2, sus4, add9, m, m7, m6, m9, dim7, m7b5). Slash chords (with alternate bass notes) are shown as the root chord. But if you need more standard chords included, you can ask me to include them, or simply create your own custom chords that get saved with the song. Click on the 'Custom chord' button on the chord window to pull up the custom chord creator window.
To create a new custom chord, select the desired instrument and select the appropriate strings and frets by clicking on them (strings with no fret specified can be designated as open or muted by clicking at the top of the string). Give your chord a custom name (no spaces or non alphanumeric characters) and press the green button to save it. If you want to create chords further up the fretboard, change the label for the first fret.
Clicking on the red buttons will remove individual existing custom chords currently saved with the song.
Custom chords for guitar, mandolin, ukulele, banjo (4), banjo (5) and cavaquinho can be created, but only the chords matching the selected instrument are shown on the song screen.
Custom chords chart diagrams are not transposable
