  Definite pitch - Wikipedia, the free encyclopedia
In music and hearing, a sound or note of definite pitch is one of which it is possible or relatively easy to discern the pitch or frequency of the fundamental.
A sound or note of indefinite pitch is one of which it is impossible or relatively difficult to discern the pitch or frequency of the fundamental.
Note that it is still possible for two sounds of indefinite pitch to clearly be higher or lower than one another, for instance, a snare drum invariably sounds higher in pitch than a bass drum because its sound contains higher frequencies.

 Percussion Instruments - MSN Encarta
Another type of pitched drum in the orchestra is the roto-tom (a modern development of the unpitched tom-tom, in which the drums can be tuned to a precise pitch by rotating the drum head).
Other pitched percussion instruments include the celesta (played with a keyboard like a piano), the tubular bells (played with leather or plastic beaters), and the mallet instruments: the glockenspiel and vibraphone (both made of metal bars), the crotales (of metal discs), and the xylophone and marimba (both of wooden bars).
Instruments without pitch used in the orchestra include a range of drums, the most prominent of which are the snare drum (or side drum), tenor drum (military in origin like the side drum, but without snares), and the bass drum.

 Philip Tagg | Pitch - EPMOW entry (2001)
Pitch, therefore, most frequently refers to the position of a note’s perceived fundamental on the axis of low to high frequency.
Until the nineteenth century, when the fixed pitch of a converged on a range between 410 and 450 Hz, keyboard players would have to transpose, wind instrumentalists take extra lengths of tubing on their travels, and string players radically retune, all in accordance with the local norm.
Ambitus basically means the pitch range or compass of a particular melodic passage, while tessitura denotes the predominant register of a particular vocal or instrumental line.

 Indefinite pitch - Encyclopedia, History, Geography and Biography
In music a sound or note of indefinite pitch is one of which it is impossible or relatively difficult to discern the pitch or frequency of the fundamental, as opposed to sounds of definite pitch.
Sounds with indefinite pitch do not have harmonic spectra or have altered harmonic spectra.
In other words, it is possible and often easy to roughly discern the relative pitches of two sounds of indefinite pitch, but any given sound of indefinite pitch does not neatly correspond to a given absolute pitch.

Cymbals consist of two thin round plates of an alloy containing 8 parts of copper to two of tin, each having a handlestrap set in the little knob surmounting the centre of the plate.
The composer indicates his intention of letting the cymbals vibrate by "Let them vibrate," and the contrary effect by "Damp the sound." To stop the vibrations the performer presses the cymbals against his chest, as soon as he has played a note.
The duration of the vibration is indicated by the value of the note placed upon the staff; the name signifies nothing, since the pitch of the cymbals is indefinite.

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.

 Dolmetsch Online - Music Theory Online - Staffs, Clefs & Pitch Notation
The clef establishes the pitch of the note on one particular line of the staff and thereby fixes the pitch of all the other notes lying on, or related to, the same staff.
In integer notation, or the integer model of pitch, all pitch classes and intervals between pitch classes are designated using the numbers 0 through 11.
Pitch classes can be notated in this way by assigning the number 0 to some note - C natural by convention - and assigning consecutive integers to consecutive semitones; so if 0 is C natural, 1 is C sharp, 2 is D natural and so on up to 11 which is B natural.

 Membranophones Percussion Instruments
Until earlier in the 20th century, tuning the timpani required tightening or loosening the calfskin membrane via screws placed around the head's perimeter; this process was rather time-consuming, so the functions assigned to the timpani were fairly limited.
Tom-toms occupy a sort of gray area between having definite and indefinite pitch, since they can be tuned to approximate pitches if necessary.
Striking the head of the instrument near the rim will result in a higher pitch than hitting it in the center, so the kind of pitch desired should be specified when composing.

 MIDI and computer music
Pitch is determined by what the ear judges to be the most fundamental wave-frequency of the sound (even when, as for example with difference tones, this is an aural illusion, not actually present in the physical sound wave).
Pitch is expressed by combining a frequency value (such as 440 Hz) with a note name.
A pitch standard is a convention of uniform pitch that is understood, prescribed and generally used by musicians at a given time or place.

 Sistro Story - Simone Fermani
In each of these sections the only note given to "sistro" is always written at the same pitch for all the time of its playing, apart from the fact of the consideration of the mean key of each section and of the changes of the harmony during all the development of each section itself.
In the "Serenade" of Count of Almaviva,(1) the note of "sistro" is written in the second line of the staff, in correspondence of the sound "G", while the main key of this section is C Major and the harmony runs mostly between the degrees of keynote and dominant of this key.
As a percussion instrument by indefinite sound mostly contributes to the rhythm and to the orchestral colour than to the harmonic development of the section in which it is provided, I discovered that in two sections of the three ones above mentioned, i.e.
