Unknown symbols piano
I am making a transcript of an old song of my land and I have only found an old score and made by hand ..
I have had no problems except with symbols that I know.
In the attached picture you can see, in keys G and F.
At no time, except later; changes 2/4 time signature.
I think it may be a form of arpeggio, I would like someone related to the world of piano doubt take me out and tell me the correct way to do it in MuseScore, thanks.
