As mentioned, Apple launched an app just for that, Music Memos, and it was a great idea but fairly niche and not updated much over the nearly five years it was out. Apple discontinued it in December 2020. Fun (well, maybe not fun, but interesting) fact: when Apple was doing press briefings for the app, they managed to get me a quote from now-disgraced musical artist Ryan Adams (who was in the middle of a career renaissance of sorts after his acclaimed cover album of Taylor Swift’s acclaimed 1989), in part because they knew I was a big fan of his. It just feels awkward nearly six years later, but at the time, Apple was leaning really hard on the respected establishment community of musicians to push the app. It’s a shame it never seemed to have much life or uptick after its release because as a 1.0/MVP it was really good. And with just a few more features, it could hack been an insanely useful app for lots of musicians who naturally use Voice Memos to capture lyrics or riffs or other content. Alas.
