Welcome to LivingPianos.com, I’m Robert Estrin. Today’s subject is, “Tempo Must be the Lowest Common Denominator.” What does this mean? You may hear a performance that starts at a nice fast tempo and everything’s going great. Then the performer gets to a section they don’t know quite as well as the rest of the piece, so they slow down in order to make accommodations. Maybe they’ll speed up again when they get to a part they know better. This is a a terrible way to perform, but I understand the temptation. If you know a piece and you can play most of it at a nice tempo that sounds great, but there are one or more parts that you can’t quite play up to tempo, you might want to play everything up to that point at a good tempo and slow down for the sections you are struggling with. But, in a performance, you never want to do that. So, what can you do in order to correct this?
