A change of a composition into another key.

Moving a section or a piece of music to a key with a new pitch.

The performance of a piece of music in a key different from the key it was originally written in. Singers will often transpose an aria (usually downwards), either to make specific high notes easier or because the general tessitura of the piece sits uncomfortably with their own vocal range. This often happens with singers in say their sixties & seventies, if they are lucky enough to still be singing. I heard Carlo Bergonzi do this when he was at the grand age of 72, wow, what a voice.

The moving of a passage of music from one pitch level to another. One can transpose a hymn down from, say, A major to F major in order to make a high soprano line more accessible to the singers; or one might transpose the Star-Spangled Banner from D-flat major (where it is easier to sing) to E-flat major (where it is easier to play). Composers also notate parts for transposing instruments (B-flat clarinet, horn in F) such that when the player plays the notated pitches the appropriate sounding pitches come out. Such a part is called a transposed part. Have a look.

The act of moving the relative pitch of a piece of music that is too low for the basses to a point where it is too high for the sopranos.

(music) playing in a different key from the key intended; moving the pitch of a piece of music upwards or downwards

The switching of the order of a pair of digits. The most common error in keyed data entry.

Shifting a piece of music to a different pitch level.

the playing or rewriting of a composition in a key different from the original.

The process of rewriting a piece of music or a scale so that is sounds higher or lower in pitch. This involves raising or lowering each pitch by the same interval.

The process of changing the key of a composition.

In music transposition refers to the process of moving a collection of notes (pitches) up or down in pitch by a constant interval. For example, one might transpose an entire piece of music into another key. Similarly, one might transpose a tone row or an unordered collection of pitches such as a chord so that it begins on another pitch.
