Tab instrument : guitar

[AdrienTorris]

Implement the guitar instrument :

• tab
• settings (capo, tuning, ...)

[AdrienTorris]

Needs arbitration : one entire part for each instrument or each part of the song contains all the instruments ?

Like :

Guitar{ // all the guitar stuff }, bass{ // all the bass stuff }, [...]

or

part1{ guitar{ },bass{ } },part2{ guitar{ },bass{ } }
