1.Check the link for the metronome Chrome extension I have included. Google for Metronome for your Chrome extensions. The one I want is offered by https://www.123metronome.com/?chromestore=1. 2. Each metronome click is a half note. This is called CUT time. Listen to my example on using the metronome and playing the rattle. You'll notice the metronome clicks on "down, up, down", and then "up, down, up". That's cut time, where note values are worth half of what they are usually. 3. Record yourself starting with the beat=60 and gradually go faster and see if you can get to the beat=100. Work with a partner if you like. You might ask the partner to clap with the metronome as long as they are accurate. It is advisable to wear headphones so you can focus on the metronome and say the words "down, updown, up, downup".
