Wait, what's a metronome? 

 

It's a practice tool that provides a steady pulse (or beat) to help musicians play rhythms accurately. The pulses are measured in beats-per-minute (BPM). 

​

A metronome can be thought of as your "practice coach". Click the metronome above to be brought to a site where you can use the metronome to keep a steady rhythm while you practice. If you start at a slow speed (maybe 50 BPM), it'll force you to keep a steady beat as you practice a difficult section. Once you've got a handle on the "slow motion" speed, start gradually kicking it up: 55...60...65...70. You'll barely notice that you're getting faster, but after a few days, you'll be up to real speed!!
