- The registers or stops used in
both the left and right hand sides could be marked using either similar
sounding instrument names or using dot markings and organ terminology.
A combination of instrument names and dot markings is also common.
- There's no single standard for
naming the stops using instrument names. It's recommendable to use dot
markings in sheet music and in order to communicate the correct setting
to an ensemble.
- The maximum number of reeds that
are used simultaneously when pressing a single key on the treble side,
determines the maximum number of stops. The same applies to the bass stops
when producing a single bass note or a note used to construct a chord.
- The theoretical maximum number
of registers or stops is 2^N-1,
where N is the
maximum number of reeds used simultaneously for a note. The -1
covers the case when no reed is sounding at all - a meaningless combination.
= 1 : Only 1 stop - no need to have a button for this!
= 2 : 3 stops
= 3 : 7 stops
= 4 : 15 stops
= 5 : 31 stops
= 6 : 63 stops (this beast would be really heavy!)
= 3 or 4 is most common and I've never seen an accordion with N
- In practice the number of stops
is usually reduced from the theoretical maximum. This is done in order
to reduce weight. Too many stops could also be confusing and some of them
would sound very similar to each other. Most players use a few favourite
- The most common dot markings are
built upon combinations of the following basic elements:
ft - The length of an organ pipe sounding one octave above
the notated value
ft - The length of an organ pipe sounding at the notated value
ft - The length of an organ pipe sounding one octave below
the notated value
- The 8 ft may have two or even three different reeds,
tuned slightly apart. Used together, the famous musette sound is produced.
Depending on the tuning distance, the tone is "wet
or dry" . Possible dot markings:
- On my Zero-Sette L40 I have the following combinations:
- This means that my accordion only uses 11 of the 15 possible
combinations with N = 4 - these are left out:
