Method for determining the exact size of musical instruments and sounding bodies in relation to frequence and sound colour, including the subdivision for half tones

摘要

Since frequency, tone and the size of space, including the accurate hole location for required bore dia in the case where wind instrument or extension in the case where brass instrument, determined by specific factor. The correlation of size, shape and tone lead to optimal sound and match characteristic. This includes the air space of all wind instruments, bell, loudspeaker, reed, bar (xylophone item), string and wall thickness and device pipe. In the case where wind instrument (hollow bodies), determines therefrom and divide true octave point again independently of all of " air-flow " and " aperture correction ". Method is fully accurately able to carry out the instrument of tuning, with any kind generation in the case where the wind instrument of the similar fingering of higher bitumen with sound property. This quite reduces the workload needed for completion product when method is to be efficiently used.
