"The number of the notes that make up a scale as well as the quality of the intervals between successive notes of the scale help to give the music of a culture area its peculiar sound quality." [6] "The pitch distances or intervals among the notes of a scale tell us more about the sound of the music than does the mere number of tones." [7]
A "complex tone" (the sound of a note with a timbre particular to the instrument playing the note) "can be described as a combination of many simple periodic waves (i.e., sine waves) or partials, each with its own frequency of vibration, amplitude, and phase". [1] (See also, Fourier analysis.)
Notes in each include an additional prime symbol below the note's letter. The octave starting at middle C is called the "small" octave. Notes in it are written as lower case letters, so middle C itself is written c in Helmholtz notation. The next higher octave is called "one-lined". Notes in it include a prime symbol above the note's letter.

A spectrogram of ascending Shepard tones on a linear frequency scale. A Shepard tone, named after Roger Shepard, is a sound consisting of a superposition of sine waves separated by octaves. When played with the bass pitch of the tone moving upward or downward, it is referred to as the Shepard scale.
In musical notation, the different vertical positions of notes indicate different pitches. Play top: Play bottom: Pitch is a perceptual property that allows sounds to be ordered on a frequency-related scale, [1] or more commonly, pitch is the quality that makes it possible to judge sounds as "higher" and "lower" in the sense associated with musical melodies. [2]
For instance, a note vibrating at 200 Hz and a note vibrating at 300 Hz (a perfect fifth, or 3 / 2 ratio, above 200 Hz) add together to make a wave that repeats at 100 Hz: Every 1 / 100 of a second, the 300 Hz wave repeats three times and the 200 Hz wave repeats twice. Note that the combined wave repeats at 100 Hz, even though ...
Traditionally in Western music, a musical tone is a steady periodic sound. A musical tone is characterized by its duration, pitch, intensity (or loudness), and timbre (or quality). [1] The notes used in music can be more complex than musical tones, as they may include aperiodic aspects, such as attack transients, vibrato, and envelope modulation.
