Chroma-based features, which are also referred to as "pitch class profiles", are a powerful tool for analyzing music whose pitches can be meaningfully categorized (often into twelve categories) and whose tuning approximates to the equal-tempered scale. One main property of chroma features is that they capture harmonic and melodic ...
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]
Harmony refers to the "vertical" sounds of pitches in music, which means pitches that are played or sung together at the same time to create a chord. Usually, this means the notes are played at the same time, although harmony may also be implied by a melody that outlines a harmonic structure (i.e., by using melody notes that are played one ...
Display of roof pitches 1:12 through 18:12 A roof made of thatch, one of the oldest roofing materials, needs a steep pitch to drain properly Some types of stone roof have a very restrictive roof pitch, which can lead to leaking Working on roofs with pitches too steep for safety requires a staging of scaffolding boards secured with roof brackets A pitch gauge measuring the slope of an asphalt ...
In music theory, pitch-class space is the circular space representing all the notes (pitch classes) in a musical octave. In this space, there is no distinction between tones separated by an integral number of octaves. For example, C4, C5, and C6, though different pitches, are represented by the same point in pitch class space.
An example, is the different concert pitches used by orchestras playing music from different styles (a baroque orchestra using period instruments might decide to use a higher-tuned pitch). Compound intervals (intervals greater than an octave) can be more difficult to detect than simple intervals (intervals less than an octave).

The pitches A=415 Hz and A=466 Hz, a semitone lower and a semitone higher than A=440 Hz respectively, were chosen because they may be used with harpsichords or chamber organs that transpose up or down a semitone from A=440. [44] These pitch standards allow recorder players to collaborate with other instrumentalists at a pitch other than A=440 Hz.
