Marvellous, making trouble too…I am learning to play a recorder…late in life, so difficult , but so satisfying when it all works and comes together..you creation so apt
Yes, they are building a treble clef sign. Making treble is the play on words you noticed. Playing the recorder is always a good thing.
A better world, if the whole world raised their children (the entire next generation) to play the recorder. (at least)
Music is the universal language. Though it is prohibited in some cultures.
p.s. It looks like one guy has his mustache on top of his nose, not under it as most wear them. Ha!
