Notation for sostenuto pedal?
I have some notation for piano indicating use of the sostenuto pedal (middle pedal see https://en.wikipedia.org/wiki/Piano_pedals#Sostenuto_pedal ) as shown here:
I cannot find anything about this in the Musescore manuals... or anywhere else for that matter. My best option so far is to add stave text, use F2 and insert something like "curve below" or elision, then position this near the note in question. e.g.
(actually that's using an un-named symbol found bottom-right in Common Symbols).
But this text is not actually associated with the note so might not stick with it when other things change? And it's a right slog adding these.
I've just found this interesting post suggesting possible use of diamond-shaped note heads and/or writing 'Sost.Ped.' http://www.pianocareer.com/piano-pedal/piano-pedals-style/ ).
Any suggestions? Is there a correct notation for sostenuto? And how do I do it in Musescore?
