Been using Complete Music Reading Trainer for a couple months now. It’s basically a music reading and sight-reading app, with a ton of different clefs and levels to work through. Pretty solid app if you’re into improving your sheet music skills.
Here’s what you do: there are like 270 different drills and exercises covering all the clefs – treble, bass, alto, tenor, and more. You can pick which ones are relevant to your instrument and just focus on those. And it’s got a leveled progression system too, so you start easy and gradually get more challenging. And the whole thing is laid out really nicely, like a video game, which makes the learning process kind of fun.
Look, if you’re trying to get better at reading sheet music, you’ll probably like this app. It’s not perfect – the ads can get a little annoying if you don’t pay – but overall it does the job. Worth checking out for sure.
