Physical Acoustics of Music
Sound spectrum is one of the determinants of the timbre or quality of a sound or note. It is the relative strength of pitches called harmonics and partials (collectively overtones) at various frequencies usually above the fundamental frequency, which is the actual note named (e.g. an A).
The spectrum analyzer is an instrument which can be used to convert the sound wave of the musical note into a visual display of the constituent frequencies. This visual display is referred to as an acoustic spectrogram. Software based audio spectrum analyzers are available at low cost, providing easy access not only to industry professionals, but also to academics, students and the hobbyist. The acoustic spectrogram generated by the spectrum analyzer provides an acoustic signature of the musical note. In addition to revealing the fundamental frequency and its overtones, the spectrogram is also useful for analysis of the temporal attack, decay, sustain, and release of the musical note.

Famous quotes containing the words physical and/or music:
“The real pleasure of being Mick Jagger was in having everything but being tempted by nothing ... a smouldering ill will which silk clothes, fine food, wine, women, and every conceivable physical pampering somehow aggravated ... a drained and languorous, exquisitely photogenic ennui.”
—Anonymous “Chronicler.” Quoted in Philip Norman, The Life and Good Times of the Rolling Stones (1989)
“Nothing separates the generations more than music. By the time a child is eight or nine, he has developed a passion for his own music that is even stronger than his passions for procrastination and weird clothes.”
—Bill Cosby (b. 1937)
