#### 3.14.5 Transpose

A music expression can be transposed with `\transpose`. The syntax is

         \transpose from to musicexpr

This means that musicexpr is transposed by the interval between the pitches from and to: any note with pitch `from` is changed to `to`.

For example, consider a piece written in the key of D major. If this piece is a little too low for its performer, it can be transposed up to E major with

         \transpose d e ...

Consider a part written for violin (a C instrument). If this part is to be played on the A clarinet, the following transposition will produce the appropriate part

         \transpose a c ...

Since from and to are pitches, so `\transpose` must be inside a `\notes` section. `\transpose` distinguishes between enharmonic pitches: both `\transpose c cis` or `\transpose c des` will transpose up half a tone. The first version will print sharps and the second version will print flats

>          mus =\notes { \key d \major cis d fis g }
>          \score { \notes \context Staff {
>            \clef "F" \mus
>            \clef "G"
>            \transpose c g' \mus
>            \transpose c f' \mus
>          }}

##### Bugs

If you want to use both `\transpose` and `\relative`, you must put `\transpose` outside of `\relative`, since `\relative` will have no effect music that appears inside a `\transpose`.
