Hi Camille,

So I used the video How to Improve Agility for Riffs and Runs | 30 Day Singer to help me gain speed with riffs and runs in the past. The thing I'm worried about is that I'm only progressing in that riff/run. My question is, is can agility/speed in one riff be like almost transferred to another riff? Also, would it be useful to practice different riff exercise patterns? Thanks and have a good day!

Yes to both questions! That riff is a pentatonic riff, which many singers use (in full or in part), so it'll transfer to plenty of future riffs you learn. But I highly encourage you to break down other riffs and keep building you "riff vocabulary". See here for steps to follow: https://www.30daysinger.com/blog/how-to-practice-riffs-and-runs.
