In music, transposition refers to the process or operation of moving a collection of notes (pitches or pitch classes) up or down in pitch by a constant interval. The shifting of a melody , a harmonic progression or an entire musical piece to another key, while maintaining the same tone structure, i.e. the same succession of whole tones and ...
The note C 4 written down produces: Comment Accordion: D ♭ piano accordion D ♭ 4: Bass accordion: C 2: Arpeggione: C 2 /C 3: Bagpipe Great Highland bagpipe: variable D ♭ 4 - D 4: A minority of bagpipes, made for playing with other instruments, are exactly D ♭ 4 (referred to as B ♭, relative to the tonic note A rather than C).
A transposing instrument is a musical instrument for which music notation is not written at concert pitch (concert pitch is the pitch on a non-transposing instrument such as the piano). For example, playing a written middle C on a transposing instrument produces a pitch other than middle C; that sounding pitch identifies the interval of ...
Chromatic scale drawn as a circle The diatonic scale notes (above) and the non-scale chromatic notes (below) [2] The twelve notes of the octave—all the black and white keys in one octave on the piano—form the chromatic scale. The tones of the chromatic scale (unlike those of the major or minor scale) are all the same distance apart, one ...
Modes of limited transposition are musical modes or scales that fulfill specific criteria relating to their symmetry and the repetition of their interval groups. These scales may be transposed to all twelve notes of the chromatic scale, but at least two of these transpositions must result in the same pitch classes, thus their transpositions are "limited".
Transposition and inversion can be represented as elementary arithmetic operations. If x is a number representing a pitch class, its transposition by n semitones is written T n = x + n mod 12. Inversion corresponds to reflection around some fixed point in pitch class space.
Because of that, all notes with these kinds of relations can be grouped under the same pitch class and are often given the same name. The top note of a musical scale is the bottom note's second harmonic and has double the bottom note's frequency. Because both notes belong to the same pitch class, they are often called by the same name.
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 ...
