Yes. with the internet you won’t need to buy a metronome, unless of course you really want those real classic ones just because.
I had a little plastic battery operated one but the interior speaker broke and so is useless now and I don’t plan on buying another one. Either way you go guys, you have to do these exercises with a metronome because of the speed increase you will gain from it. there’s just no better way…believe me. It’s what really allowed me to break through in this regard many years ago.
