==Transposition and modulation==
{{confusing section|reason=transposition and modulation are different;|date=August 2018}}
Composers transform musical patterns by moving every note in the pattern by a constant number of scale steps: thus, in the [[C major]] scale, the pattern C–D–E might be shifted up, or [[transposition (music)|transposed]], a single scale step to become D–E–F. This process is called "scalar transposition" or "shifting to a new key" and can often be found in [[sequence (music)|musical sequences]] and patterns. (It is D–E–F{{music|sharp}} in Chromatic transposition). Since the steps of a scale can have various sizes, this process introduces subtle melodic and harmonic variation into the music. In Western tonal music, the simplest and most common type of modulation (or changing keys) is to shift from one major key to another key built on the first key's fifth (or dominant) scale degree. In the key of C major, this would involve moving to the key of G major (which uses an F{{music|sharp}}). Composers also often modulate to other related keys. In some [[Romantic music era]] pieces and contemporary music, composers modulate to "remote keys" that are not related to or close to the tonic. An example of a remote modulation would be taking a song that begins in C major and modulating (changing keys) to F{{music|sharp}} major.
