When One Note Is Above Another Note by an Octave,the

Multiple Choice

When one note is above another note by an octave,the frequency of the higher pitch note is double that of the lower pitch note.The word octave may make you think that there are 8 steps from the lower note to the one an octave above.But wait! How many steps are there on a piano from middle C to the next C above? Each key is a step.If each next key is a step,how many are there? Middle C is a white (W) key and the next note above is a black (B) key.Starting at middle C on the piano the sequence of key we go through to get to high C,is BWBWWBWBWBWW,the last key being high C.Count 'em.That's 12 steps.If the multiplying factor of the frequency for the next step is the same for each step,what is that multiplying frequency? All you need is given in this problem statement.

A) 10^1/12
B) 12^1/8
C) 2^1/8
D) 2^1/12
