SLIDE SET - INSTRUCTIONAL SESSION TWO
The ten reed plates in each of the two rows are matched to the ten treble buttons.
When a button is pressed, and the bellows pushed (for example), the air flows through two holes to activate two very similar metal reeds (one on each opposite reed plate). Longer reeds give lower-pitched notes, and shorter reeds give higher-pitched notes. |
For this single-row button-accordion, two of the bass buttons (1 & 3) connect by a lever mechanism to elongated hole covers and control the flow through three holes, corresponding to the three notes that make a chord.
The other two (2 & 4) connected to smaller hole covers and control the flow past two bass reeds that give us the bass-note sound. |
Here we can see the three holes that are uncovered when bass button 1 is pressed. On the other side of these three holes are three reed plates, with three reeds sounding on the push and another three sounding on the pull.
Playing multiple notes at the same time gives us a chord. A three-note chord is sometimes called a triad. |
