A diatonic accordion is made of three parts : bellows are located in the central part is the . They produces the air movement when the instrument is pushed (bellows compression) or pulled (bellows extension).
The performer's right hand moves over a set of buttons. These buttons are numbered according to their location in row and column. Each button, when pushed, can generate two notes : one when bellows are compressed, the other when bellows are stretched.
The performer's left hand can use another set of buttons. Some of them play a chord (several notes), some other only a single note called "bass". Here again, the bellows movement changes the pitch of played note(s).
Each kind of accordion can have a different number of buttons, and a different tuning (played notes for each button).
Display
Right hand (plays the melody) :
Tablatures display can follow two standards : column system or
push/pull system.
The number written on tablature is always the number of button row
to use. The first one is the topmost row of the instrument.
. column system :
Each tablature line matches a button column.
If the button number is underlined, it means the button is played "pulled". If not underlined, it means the instrument is pushed.
. push/pull system :
Instrument is pulled when the button number is written on the upper line of the tablature. It is pushed when the number is written on the bottom line.Button columns are indicated by as many apostrophe mark as column number :
- no apostrophe mark for first column,Left hand (accompaniment)
- one apostrophe mark for second column,
- two apostrophe marks for third column (if any).
