STRADELLA BASS DIAGRAM
- This bass system is called Stradella
(standardbas in Swedish) and is the most common accordion bass system at
least in Sweden.
- The buttons in the bass rows produce
single notes (several reeds in different octaves may be combined, however).
There's only one octave available using a given registration - several
keys produces the same sound.
- The buttons in the chord rows combine
several notes into a chord. The same reeds are used for different chords.
7th and dim chords often use only three notes even though four are needed
- Other chords may be formed using
left hand chord combining.
- Melody (free)
bass systems are not common and are used mostly by professional players.
- Basically you have only four chord
types but other types are possible using combinations of keys. Intermediate
or advanced players compensates this using right hand chords and/or bass
- The number of buttons is 120 (20*6)
on a full size instrument. You really don't need more than 72 (12*6) in
order to play all bass notes and corresponding chords. Using only 72 basses,
however, is more demanding since you have to do unnecessarily long jumps
in certain keys or when doing bass runs.
