Remember the Steps to Mastery:
1: Checking Time Signature
2: Clap Counting in Pairs
4: Checking Key Signature
Once you've done each step 3 times mistake-free, you're ready to move on! Listen the the recording, hum along to teach yourself what to listen for, then play with it!
If it doesn't go well, ask yourself which part in particular you're struggling with. The rhythm? The note names? The fingerings? Once you've isolated the problem, use the steps to mastery to fix it!
