smartChord supports beneath the common musical notation also Solfège and Nashville Number System. In the ‘Names’ settings, you can choose your preferred tone names:

Either the common musical notation: C-D-E-F-G-A-B

or Solfège: Do-Re-Mi-Fa-Sol-La-Si

or Nashville Number System: 1-2-3-4-5-6-7
(please see https://en.wikipedia.org/wiki/Nashville_number_system)

This setting affects every feature. The chords, the scales, the ear training, … even the songbook. You can use every song from the internet which is mostly in the notation C-D-E-F-G-A-B and smartChord shows you Do-Re-Mi-Fa-Sol-La-Si or 1-2-3-4-5-6-7

SO instead of SOL

smartChord uses the valid abbreviation SO as an equivalent to the more common SOL. We have chosen this because there is less space for the note names. Furthermore, it makes things much easier and more consistent if all tone names have the same length.
