The sense of pitch depends on the intensity of the tone, as shown in the graph; below 1000 Hz, pitch tends to drop with increasing loudness, and above 1000 Hz, tends to rise.
The pitch ascribed to a complex tone or sound may not necessarily correspond to a frequency that is physically present in the sound.
In summary, Schouten has stated, "The pitch ascribed to a complex sound is the pitch of that component to which the attention, either by virtue of its loudness or of its contrast with former sounds is strongest drawn.

There are basically two ways to use a sound sample, in HyperCard or anywhere else: as a sample of a wave of definite pitch, or as a miniature "tape recording" of some sound that is not intended to be used as a sample of indefinite pitch.
Definite Pitch To play a sample at the correct pitch, HyperCard assumes two things about the sample: it was sampled at a rate of 26.32 KHz, and the associated wave was playing a pitch of 261.63 Hz, when it was sampled.
Indefinite pitch Sounds which are not samples of definite pitch (for example, a thunder clap or the sound of your mother saying "hello") should not need to be made to match pitch.

 Columbia Encyclopedia - tone. - AOL Research & Learn
In music, a tone is distinguished from noise by its definite pitch, caused by the regularity of the vibrations which produce it.
Pitch is determined by the frequency of the vibration, measured in cycles per second; intensity (or loudness) is determined by the amplitude, measured in decibels.
When two fairly loud tones of equal volume but different pitch are sounded together, a fainter resultant tone, representing either the sum of their two rates of vibration (summation tone) or the difference (difference tone) may be heard.

 Pitch paradoxical
The pitch of a harmonic tone is defined to be its fundamental frequency, which is the frequency of the pure tone which has the same pitch.
The above definition of pitch still holds operationally, but the fundamental frequency is not directly measurable, and must now be derived from the the higher harmonics.
As confusing as pitch is for a single tone, the difficulties are compounded with multiple tones, multiple voices or instruments.

 Music-Science Glossary
is the pitch with a fundamental frequency of 550 Hertz.
For example, "5:4" describes a relationship in which the higher pitch has a fundamental frequency which is 1.25 times that of the lower pitch, and "3:2" describes a relationship in which the higher pitch has a fundamental frequency which is 1.5 times that of the lower pitch.
Although pitches, like frequencies, can be any of an infinite continuum of values, only a handful of related definite pitches are considered musically useful within a particular musical system; the actual fundamental frequencies of a set of pitches depends upon the tuning being employed and the reference frequency being chosen.

If a complex tone is comprised of several pure tones whose pitches are an a harmonic relation (ie each is some whole fraction of another), the complex tone tends to sound like one tone with a certain pitch and timbre.
If the pitches of the pure tones are not harmonically related, or are very high harmonics, the complex tone may have not have a definite pitch.

 Timpani - MarchingWiki
If the head is not clear, the pitch of the drum will rise or fall after the initial impact, and the drum will produce different pitches at different dynamic levels.
Timpanists who are not blessed with absolute pitch obtain a reference pitch from a tuning fork, pitch pipe, or even a note played by another instrument in the course of the performance, then use musical intervals to arrive at the desired note.
However, every time the drum is moved, the overall pitch of the head changes, thus the pitches must be re-marked on the gauges before every performance.

The pitch of the note is related to the fundamental frequency of the complex tone.
Since they don’t measure pitch (but only the timpanic pressure of the head at specific points) and since pressure doesn’t determine pitch, these pressure readings are probably best used as a guide to get you in the general range of the drum’s optimum sound rather than a mechanism for fine tuning.
