A# 7th Flat 9th

The chord calculator automatically determines every mathematically possible fingering for a chord based on the options you specify. In most cases, you will only need to adjust the "root" and "chord" pulldowns. The defaults for the other options should suffice for most situations. Adjust the "bass" option if the chord has a non-root bass note (e.g. an inversion.) Chord diagrams can be labelled with letters or scale degrees. Be careful when adjusting the advanced options as they may result in chords that are very difficult to play.
