By means of a high speed oscillograph, sound waves were recorded of the principal orchestral instruments. The harmonic contents of the orchestral tones were determined by means of the Henrici harmonic analyzer. Two main problems were suggested for solution. First, as we increase the fundamental pitch, what is the resulting qualitative change in the structure of the tone? In the second place, what changes are evident as the intensity of the tones is varied?
