not that easy. this is john coldtrane playing a I-IV-VI-II-III progression going at about crotchet=240.
Im not doubting your skills as a transcriber, its just ive got perfect pitch and even then i just cant figure it out.
ive figured out unsquare dance so dw about that. i just really need an actual copy of the sheets for giant steps. i need to know whether the chord im playing is a dim7 or an alt7b9, or whatever. only the actual sheets can give me that info.
thanks for the offer though! i really appreciate it!
I-IV-VI-II-III progression? I didn't hear that anywhere in Giant steps...
First off - nothings too fast for me

(Anthropology is meant to go at about 300bpm)
Second - perfect pitch is rarely useful for more than the starting key/note/chord. I have both perfect and relative pitch, and seldom use perfect over relative. Most brains don't work that way (as far as i know...we're all different).
Third - In my experience, lead sheets don't specify chords as much as "altered 7th b9"; they tend to just give you the letter name, usually a 7, and either maj, min, or dom (sometimes dim or aug, depends) It's often because chord alterations can be done over other chords or even improvised on the spot. Sheet music transcriptions or scores will usually give you the whole chords down to the last note, though. Although, i have seen plenty of lead sheets that do as well.
I don't think it really matters anyway, since there aren't really any altered chords or diminished chords in giant steps, lol.
Fourth - you should slow it down; because i reckon you can work it out. I'm just guessing because i just worked out a huge chunk of the middle section of giant steps with relative ease (not trying to brag). It's not that complicated when you think about it; most thinks are in key but sound out of key because of the rapid 2-5-1s to seemingly unrelated keys (Coltrane just can't sit on one tonal center, can he? lol). When you slow it down, it seems simpler. That's what helped me when i started transcribing, anyway (you probably know this).
Anyways, i was pretty pissed after working it out when i found this;

it's exactly what you want, sheet music for the lead and chords. Plus, it's animated, which looks awesome. But i realized that the piano solo isn't written. Still, better than nothing, right?
Also, i had a listen to unsquare dance (i had never heard it before), and i'm really digging the whole 7/8 thing. But really, it's just a basic twelve bar (and i mean basic, like '1,4 and 5' basic). Albeit, everything else really rips on top of it (thats a good thing).
Anyway, enjoy.
