LilyPond Notation Reference: 2.2.3 Accordion

### 2.2.3 Accordion

This section discusses notation that is unique to the accordion.

#### Discant symbols

Accordions are often built with more than one set of reeds that may be in unison with, an octave above, or an octave below the written pitch. Each accordion maker has different names for the shifts that select the various reed combinations, such as oboe, musette, or bandonium, so a system of symbols has come into use to simplify the performance instructions.

Accordion-discant symbols

Accordion discant-specific symbols are added using `\markup`. The vertical placement of the symbols can be tweaked by changing the `\raise` arguments.
