Now that you've learned a bit about rhythm and note durations, the best way to get a handle on them is to practice using them. Below is a link to this lesson's video, as well as additional practice.
In this video I guide you through some of the rhythmic practice exercises from our course materials.
To the right is an online rhythm trainer in which you can either match a rhythm to audio, or audio to a rhythm. You can change how many rhythms you want included in the exercise. This doesn't use all the note values that we covered, but it's helpful for practicing with subdivisions of the beat.
