An octave is what encompasses the major scale. There are seven different notes in that scale. The eighth note is a repetition of the first, but an octave higher (the eighth, hence the octave from the Latin "octus" meaning eight as in octopus, which literally means eight-footed.)<br /><br />Now all you need to add to this are two more very basic facts: <br /><br />1. Musical pitches are physical vibrations. That means some physical movement back and forth at some rate per second, which we call frequency. For example, the international standard for the concert A an orchestra tunes to is 440 vibrations for second, hence the term A440.<br /><br />2. Any note repeated an octave higher has double the frequency of its lower counterpart. In other words, if we sound the A an octave above A440, it will vibrate at a rate of 880 per second. An octave lower would vibrate at a frequency of 220 Hz, another way of saying vibrations per second, since Hz is an abbreviation for Hertz, which simply means cycles per second.<br /><br />So when we touch a vibrating guitar string lightly at the exact midpoint, it will sound an octave above its normal frequency of vibration. That corresponds to the eighth note in the scale above the normal pitch of that string. <br /><br />This is physically equivalent to having two identical strings half as long tuned by the same tension on the string. The tension is included simply because changing the tension of a string, for example tightening or loosening the tension of a string with the tuning pegs at the end of a guitar neck, changes its rate of vibration. Tighter strings vibrate at higher frequencies and correspondingly higher pitches, while looser strings vibrate at lower pitches. <br /><br />The scientific part of this used to be junior high science in the 1950s. I don't know how much they teach at that level now. Not much, I would guess. But all of this is extremely basic musical knowledge; certainly not anything we could justifiably call "in-depth knowledge". Musicians who fail to understand these simple facts may know how to play, but that represents only mechanical ability to manipulate these factors without any understanding about how any of what they're doing actually works.Roberthttps://www.blogger.com/profile/13070586117973549191noreply@blogger.comtag:blogger.com,1999:blog-8876476586808141865.post-68265270509375732672009-06-16T12:19:27.379-07:002009-06-16T12:19:27.379-07:00What I have presnted here are excerpts of the earl...What I have presnted here are excerpts of the early investigations about the nature of sound of the Pythagoreans,based on the relationship between music-maths and physics.<br /> An indepth analysis of the topic would require a lot more than a mere gist of what you had read in my article.Thank you.GayathriVeenaagayathrihttps://www.blogger.com/profile/17870493124318092517noreply@blogger.comtag:blogger.com,1999:blog-8876476586808141865.post-57777074776987160502009-06-15T23:41:29.575-07:002009-06-15T23:41:29.575-07:00Hi Veena Gayathri Ji,
