Reply To: Reed spacings and chamber dimensions
Hi MM
Chamber Width
I measure the chamber width with a calliper, though you can get a good idea with a ruler. In this section of a melodica below, its the measurement highlighted by the green arrow:
Reed Spacing
I get a rough idea of the reed spacing by measuring the distance between the left edge of the air cavity, to the left edge of the next air cavity, as illustrated by the red arrow above.
You can make this even more accurate by measuring from the left edge of the first cavity, all the way to the left edge of the last cavity. If there are 32 cavities, you can divide the number by 32, as in the blue arrow below:
