Rehearsal marks (sometimes called Rehearsal Letters) can be used in a number of ways. e.g.
Rehearsal marks are a type of system text. In a full score they show only above the top staff of a system, but appear in all instrument parts.
Rehearsal marks can be added to the score in two ways: (1) manually, allowing you to name them as you wish, or (2) automatically, which ensures that they are named in sequence
To create a rehearsal mark manually and give it a name of your own choosing:
MuseScore can name the Rehearsal Marks automatically. Do either:
Notes: (1) By default, marks are added in the sequence, A, B, C etc. (2) To change the format of subsequently-added marks (to lower case letters, or numbers), edit the previous rehearsal mark accordingly. (3) Marks added between existing rehearsal marks append a number or letter to the previous mark: it is a good idea to apply the Resequence command afterwards (see below).
If you want the rehearsal marks to be displayed as measure numbers:
MuseScore allows the user to automatically re-order a series of rehearsal marks if they have got out of sequence for any reason. Use the following method:
MuseScore automatically detects the sequence based on the first rehearsal mark in the selection—all rehearsal marks in the selection are then altered accordingly. The following sequences are possible:
See Find / Go to (Navigating your score).
In most full scores any Rehearsal marks are shown only above the topmost staff of a system, but appear in all the generated instrument parts. If duplicate marks are required on lower staves they should be added as staff text.
Some templates have an additional feature, e.g. Symphony Orchestra or Classical Orchestra, see the list of templates in Staff Text and System Text chapter. On a new score created using either of the two templates listed abve, when you create a rehearsal mark above the top staff, an identical one is automatically added just above the string section. If either instance of the mark is edited the content of both is updated. If either one is removed, both are removed.
By default, rehearsal marks appear in a large bold font, enclosed in frames, and aligned to the center of the start barline of the measure. You can edit the default text properties from Format→Style→Text style.
The properties of selected rehearsal marks can be changed in the Properties Panel.
