This study addresses the question of pitches and pitch structures that may have been played on the excavated instruments, assessing string lengths and their implications as well as searching for a plausible effective length for the aulos including its reed, based on computer-modelling the behaviour of the oscillating air column. The results are discussed in the context of our present knowledge about pitch ranges that were typically used in ancient music.
