When you share a PlayScore 2 Playable Score Document you are sharing the whole PlayScore 2 experience. Anyone who receives your document will be able to play it and follow the music just as you do. This is free; they don’t need a subscription. They will be able to start from any measure, change tempo, create loops and more.
From the Documents screen, tap Select and then one or more document thumbnails (for Android devices, long-tap the document)
Tap the share/export icon
Send the document, eg by email
When someone receives your document, as long as they have an iPhone, iPad, a mac (with the M1 chip or above), a Windows 11 PC or Android device they will be able to play it. To do this they must first have downloaded PlayScore 2 from the app store for their device. This is free; they don’t need a subscription. If the document comes in an email they just tap on the attachment and choose Send to PlayScore 2. On a Windows PC the recipient should save the attachment somewhere and use the right-click command Send to PlayScore 2.
Locking
Sometimes it is useful to prevent the recipient from accidentally changing the Document. Say you are a choir leader and you want to send Play-my-part voice separations to your singers. You might want to lock the Document so it can’t be changed unintentionally. A locked document can be played but not altered. To lock a document just tap the padlock symbol 
top right before export. Note that if the recipient does not have a subscription they will receive the document locked but still playable by default.
