- Instruments whose sound source is either an edge tone or a reed mechanism to resonate a column of air.
inlays in the fingerboard of some stringed instruments. These are
placed perpendicularly to the strings at premeasured places along the
length of the fingerboard to fix the length of the string when the
finger presses behind them.
caused by eddies of air which are produced by a stream of air blown

- The windpipe or tube from the lungs to the throat and mouth. The vocal folds lie at the top and across this forming the glottis.
- Suppression of vibration by applying physical restraint. Decrease in amplitude because of interfering forces.
