octave name beside the note

[sugizo]

when play in choir better to have octave name beside the note e.g. in standard choir usually use SATB (Sopran Alto Tenor Bass) which every vocal characteristic (male/female) has it's own range (base on octave)
e.g. which fretboard must be press to play melody with tenor vocal on major third tuning

That's a nice idea. Should be reasonably easy to add.

please consider to change tuning-module.ts too, because you must define the tuning with it's octave too, e.g.
E2–A2–D3–G3–B3–E4

in music octave can be written as scientitic and helmholtz
western music commonly use scientific, but it's nice to have an option for some people who learn the octave base on helmholtz pitch notation

So, technically this would involve adding octave numbers to the note data definition.
Interesting about helmholtz, I wasn't aware of that.
