In music, an octave (Latin: octavus: eighth) or perfect octave (sometimes called the diapason) [2] is an interval between two notes, one having twice the frequency of vibration of the other. The octave relationship is a natural phenomenon that has been referred to as the "basic miracle of music", the use of which is "common in most musical ...

Musical symbols are marks and symbols in musical notation that indicate various aspects of how a piece of music is to be performed. There are symbols to communicate information about many musical elements, including pitch, duration, dynamics, or articulation of musical notes; tempo, metre, form (e.g., whether sections are repeated), and details about specific playing techniques (e.g., which ...
Namely, B—D is a third because in any diatonic scale that contains B and D, the sequence from B to D includes three notes. For instance, in the B-natural minor diatonic scale, the three notes are B–C ♯ –D. This is not true for all kinds of scales. For instance, in a chromatic scale, there are four notes from B to D: B–C–C ♯ –D.
A lead sheet A chord chart. Play ⓘ Percussion notation conventions are varied because of the wide range of percussion instruments. Percussion instruments are generally grouped into two categories: pitched (e.g. glockenspiel or tubular bells) and non-pitched (e.g. bass drum and snare drum). The notation of non-pitched percussion instruments is ...
Below is a comparison between the first 31 harmonics and the intervals of 12-tone equal temperament (12TET), octave displaced and compressed into the span of one octave. Tinted fields highlight differences greater than 5 cents ( 1 ⁄ 20 of a semitone), which is the human ear's " just noticeable difference " for notes played one after the other ...
The implementation of chords using particular tunings is a defining part of the literature on guitar chords, which is omitted in the abstract musical-theory of chords for all instruments. For example, in the guitar (like other stringed instruments but unlike the piano ), open-string notes are not fretted and so require less hand-motion.
Some scales use a different number of pitches. A common scale in Eastern music is the pentatonic scale, which consists of five notes that span an octave. For example, in the Chinese culture, the pentatonic scale is usually used for folk music and consists of C, D, E, G and A, commonly known as gong, shang, jue, chi and yu. [14] [15]
