La malle aux accordeons

Mechanical principles of the accordion: air flow paths

The Melody: Button, Pallet.

As described previously, the reed rank is a kind of wood harmonica on which reed-fitted plates are laid. 

When air flows through the rank in the right direction, the reed vibrates.

Each button on the accordion is connected to a mechanism which allows one or more pallets to be lifted.

Pressing a key on the fingerboard raises the pallet and allows air to flow across the reed.
