Speed/Pitch Relationship

[AcidQueen]

How much, in percent, would I have to change the speed of a note to change the pitch a half step?

[AcidQueen]

It sounds to me like 5% is a half step.

what are you talking about

It's not that hard to get, kid.

just get your guitar out and try a few different speeds untill it sounds right, i wouldnt know off the top of my head

how do you measure the change of speed in a note? I suppose I can answer your question. Pitch is defined as our perception of a note frequency. Frequence is measured in hertz (one cycle a second). We will use concert pitch as our example, which is A=440 hertz, or 440 cycles a second (A4).

I don't know the exact measurements, but with a little math I am sure we can figure it out. If you multiply 440 by two you will find yourself and octave up from A4. Thus we can infer that if you divide 440 by 12 we can come up with the increments needed for each 12 tones in a chromatic scale (36.6667). So (36.6667)(100)=440X and that would make your percentage needed to raise a pitch by half a step 8.3333%.

I hope that's right haha we need more questions like this.

That was great thinking.. well done.
