Editing Accordion (section)

====Pallet mechanism====
The accordion is an [[aerophone]]. The keyboard mechanisms of the instrument either enable the air flow, or disable it:<ref group="notes">Illustration made with reference from a similar illustration that can be found in both ''Det levende bælgspil'' (p. 9) by Jeanette & Lars Dyremose (2003), and ''Harmonikaens historie'' (p. 35a) by Bjarne Glenstrup (1972, The University of Copenhagen, Faculty of Music)</ref>

[[File:Accordion button mechanism.svg|upright=3.4|thumb|center|A side view of the pallet mechanism in a piano accordion. As the key is pressed down the pallet is lifted, allowing for air to enter the tone chamber in either direction and excite the reeds; air flow direction depends on the direction of bellows movement. A similar mechanical pallet movement is used in button accordions, as well as for bass mechanisms such as the Stradella ''bass machine'' that translates a single button press into multiple pallet openings for the notes of a chord.|alt=Accordion; cross-sectional view]]
