I wasn't familiar with Uncle Rod's Ukulele Boot Camp before, so I looked it up. (
Here's the link.) I'm at the stage where I barreled into this wanting to learn a bunch of songs, only to discover that I'd picked up enough bad habits that it's worth going back to the beginning for, uhm, most of it.
This looks like a great resource!
One of my favorite tips is saying the chord names aloud while you're practicing. At earlier points in my ukulele journey, I found myself a couple of times going, "Ugh, F#m sounds hard" only to discover that not only is it NOT hard, but I had already played several songs with it, and forgotten that I'd learned it! There's a lot of one- and two-finger chords that are the same way -- "Wait, you get Fadd9 by taking AWAY one of the fingers while playing F??? Oh yeah, I've already done this in another song."
I'm still glad that I spent a while learning some songs. I need that motivation to want to keep plowing through the practice, so I try to have practice sessions partly focused on drills like Uncle Rod's, but also with a song or two in the mix. I also look at songs that are over my head, identify the trouble chords and/or transitions, and make those part of the next round of drills BEFORE I start applying myself to the song. (Penny Lane, I'm looking at you!)
Another good thing to check out is “Songs with Chords You Already Know,” which is exactly what it says on the tin.
I tried googling this and got back a bunch of things that didn't seem like what you're talking about. The whole first page of results is the CHORDS to the SONG whose title is "You Already Know." LOL Accurate enough, but not what you mean, I think. Can you tell me what this is? A book? A site?
