Click on the photographs above to hear the sounds of (left to right) the alto recorder, the tenor krummhorn, and the clarinet. For those of you who have never heard the sound of a krummhorn (sometimes spelled crumhorn) click on Crumhorn music, please. (A brief discussion of the instrument and the music is included.)
Below are sets of three wave shapes and Fourier spectra belonging to these three instruments, but not necessarily in the same order.
Wave shapes (left to right) a, b, and c:
| (a) |  |
(b) |  |
(c) |  |
Fourier spectra (left to right) a, b, and c:
| (a) |  |
(b) |  |
(c) |  |
You are to determine which of the above wave shapes and spectra correlate with the sounds of each instrument:
