This article is about adding scores to sets and groups. See Groups.
You may have noticed a 'This score appears in' section on the right of other people’s scores. Under that, some number of sets and/or groups may be linked to.
If you have several related scores—for example, songs from an album you’re recording, or piccolo/contrabass duets, or transcriptions of Beethoven symphonies—you can create a set for them with the 'Add to/remove from set' link available under the ⫶ menu on the right of the score. After the score is added to a set, anybody viewing one of those scores will see 'This score appears in' that set and can click that link to see the rest of the set.
Public groups are listed at https://musescore.com/groups. You can join groups or create new ones. If you are a member of a group, then you can share your score specifically with other people in that group by clicking the 'Add to/remove from group' link available under the ⫶ menu on the right of the score. With a free account, you can share a score with up to five groups at a time; with a Pro account, you can share it with up to thirty groups. For more details on groups, see Groups.
