Assuming you're tuned in fourths, you work out how many notes your bass can produce. Using the formula:

Notes= 1+ number of frets + 5(number of strings-1)

So my 24 fret 5 string bass tuned in fourths makes:

Notes= 1+24+(5x4)= 45

45/12 (12 semitones per octave)= 3 full octaves and an extra 9 semitones.

So four string, 22 fret would be:

1+22+15= 38 notes, which is 3 full octaves and an extra 2 semitones.

Pretty sure that's the formula anyways.

Edit: This doesn't cover harmonics.

Surely it would be one extra semitone, not two?

You know you are dead sexy when you do maths...


And yes, he's correct.

Well, the lowest note you've got is an E (assuming standard tuning, same works so long as you're tuned in fourths, you're just moving it all around some), and the open G is 1 octave and a minor third (four semis) up from there. So unless you do harmonic wizardry higher than the fretboard goes, you've got 1 octave plus 4+22=26 semitones. But in that 26 notes is 2 12's, each of which is an octave. So you've got 1+2=3 octaves, and 2 semitones (26-24) left over on top.

edited- I can't count octaves for some reason.

Simply put:

N= 1+f+5(s-1)

Where N=notes, f=frets, s=strings
