Using Sox Play to Help Learn Guitar

I mentioned last month that I'm learning guitar. It's been going well and I'm having fun. But I've gotten to the point where I sometimes get chords confused: a song is listed as using E major and I play D major instead.

Also, it's important to practice transitions between chords, which is easy when you only know three chords; but with eight or so, I had stopped practicing transitions in general and was only practicing the ones that occur in songs I like to play.

I found myself wishing I had something like flash cards for guitar chords.

Someone must have already written that, right? But I couldn't find anything promising with a web search. And besides, it's more fun to write programs than to flail at unhelpful search engines, and you always end up learning something new.

Command-Line Metronome

I mentioned before that I'm taking beginner guitar lessons. Justin recommends using a metronome for some of the practicing, and that makes sense: I notice that sometimes when I practice I try to go too fast, which might or might not be good for learning the chord changes but it also leads to more mistakes and worse chord quality.

There are probably lots of phone metronome apps, but I'm usually practicing near my computer (where I watch the lessons and where I keep all my notes on chords and rhythms for particular songs), so I thought it would be nice to have a metronome on Linux.

Transposing a Song in Audacity

I've been learning guitar. I've tried several times in the past without much success, concluding that although I love music, making it is just not where my talents lie. But this time I'm following a course (Justin Guitar), doing things more or less in the recommended order rather than jumping around randomly. It's fun, and I'm practicing regularly and feel like I'm making progress.

So far I know about five chords, and surprisingly, there are a lot of good songs you can play with only three to five chords. But if you want to play along with a record, some songs need a capo (one of those little dinguses you can clamp around the guitar's neck) to map the chords to ones that are easy for beginners to play.

I don't have a capo. Justin Guitar has a phone app that supposedly can transpose songs, but I wouldn't know about that, because it doesn't work on my phone, just spins forever any time I try to load a song. But I do have a computer; can't I just take a recording and transpose it?

Yes! It's easy in Audacity.
