Dear Carlos, Regarding your 1st question - A "perfect 5th" is a musical term that means the distance formed by the 1st and 5th notes of a diatonic scale. example is C and G. C and Gflat would be a diminished 5th, and C to Gsharp would be called an augmented 5th. A "pure 5th" is a term used by tuners to mean a 5th that is beatless. A 5th that has beats is either contracted or expanded. A musician would consider a 5th with beats as being out of tune but would still call it a perfect 5th. Sorry, but I do not understand your 2nd question. Try again and reword the question. Regarding part 3 - 1.5 beats *does* mean one and a half beats per second. NOT ONE BEAT IN 5 SECONDS. I hope this helps Carlos Howard S.
