Ds plays the piano and is doing his ABRSM grade 4 this summer. He's 11 and off to secondary in September. He wants try out a different activity next term that clashes with his usual music lessons. He thinks that he will go back to the piano in the spring term. Is it a really bad idea to let him have a break from lessons? Will he unlearn everything in 6 months? Has anyone's dc ever had a break from an instrument and then successfully returned to it?
