I have always liked "Time is Tight" by Booker T.
A great 60's organ sound.
Sheet music is not free for this one and looking at the sample evaluation page, it looked complicated.
So this is what I did . .
I listened to the song and figured out it was in the key of C.
I played a few bars and stopped and wrote down what I thought. Starts in G for 4 beats followed by C and G and back to G. = first 3 bars.
The first G is below middle C and that clashes with my split point. So I moved it up an octave. Sounds perfect!
I transferred my writings to blank staffs. I tried it out on my keyboard. . . Hey! Got it right!
Working out the chords was tricky. Trial and error but C, G and F majors all work superbly.
So I continued the whole song . . stop, start, rewind, pencil to paper, play bits on my keyboard, play a few bars, stop, start, rewind, replay etc.etc . . Get the picture? Taken a few days so far but as you can see . . not quite finished.
I know I have many mistakes in there . . for example ties are wrong etc. . but it makes sense to me.
Have a look at my work.
