I'm learning Nick Drake's - Things behind the Sun, which I'm really enjoying; great lesson Neil.
I've gotten to the point where I can play each of the parts. I've played it all the way through at about 60% of speed quite a few times. All of the parts, including each time you play the verses are different enough that I still need to look at the music to remember what I'm playing. I haven't memorised it yet. GPro has been great for doing this. BTW - I'm not playing exactly what's written but I still need to know basically what I'm suppose to be playing.
I'm now at the point where I'd like to play against the original so I can get the words into my head (even if I don't sing them yet) and sync the playing with them, before I start to speed it up more. With most songs I can just flip through the music using ForScore on my iPad and my Cicada PlagFlip. But, the structure of this song is complex enough that that's not really working for me because you need to go back and forth between pages, it's not just in one direction. It's possible I need to try harder. Yep I realise that.
Using a program that slows down the original (the Amazing Slow downer in my case) and GPro at the same time is mostly working. However, the speeds are slightly mismatched even though I'm setting them to the same %. I suspect that the speed slide in GPro is more sensitive than it shows; e.g. It's actually set to 65% rather than 60% as indicated.
I have memorised lots of it, but there are about three or so...sections where I need to look at the music in particular; e.g. the solo, end of the 3rd and 4th verses and the end...and...something else.
Another approach I use is to have all of the pages up on my mac at the same time. There's four pages here so ... My eyes are too old to see music that small.

Blah, blah, blah ...
So I'm wonder whether there's an easier and more practical way to do this that I'm just missing.
How do you approach practicing a song with a complex structure against the original when you haven't memorised the music yet?
Thanks
