I just finished learning the melody of this tune from The Real Book Sixth Edition. I have a few questions about it: 1. Who wrote it? I see a lot of people online debating on who wrote this piece. I see people talking about how someone stole it and took credit from its original owner. 2. Is it swung or straight 8ths? I also hear a lot of debate over whether it should be played swung or straight. 3. What tempo should it be performed at? 4. When playing this (or anything) on bass, should there be a certain string to play a certain note on? Since I've been practicing it rather slow to get the parts down, I'm afraid that some speed will be limited by choice of positioning. Or can anyone send a tab (I never use tabs, but it may help in this instance) of the easiest or most recommended way of playing this? Whenever I find a line that is strictly a scale or arpeggio being superimposed over the chord, I usually just go with one of those common fingerings for the arpeggio or scale. It's the large skips and chromatic sections that make me wonder if it can be executed more easily, or at least with greater precision at full tempo. An example is at the very beginning of the tune, after it skips from an A to a low Bb (I think, I don't have the sheet or my instrument on me), should I have already changed positioning to play this line lower on the A and D strings rather than higher on the E and A strings? 5. Finally, if I were to record this, would it be wise to play the chords on bass in a high register, most likely excluding one or two notes from the chord? Would voicing these chords in a certain way prove to be beneficial or feasible?
