  • 相对于 Matlab,Octave如何? - 知乎
    octave唯一的优点也就是占内存小了(< 500M),然而不知是不是安装的姿势不对,每次打开软件 跑个小命令,简直比PS和AE还慢。
  • What is an octave? - Music: Practice Theory Stack Exchange
    An octave is simply an interval created by the use of the factor 2 instead - e g if we started with our 100Hz note again, and we wanted to go up an octave, we would double the frequency, taking us to 200Hz If we wanted to go down an octave, we'd halve it, taking us to 50Hz Why is this factor of 2 so special?
  • tuning - Was the term octave coined after the development of early . . .
    Was the term “octave” coined after the development of early music theory? No As shown below, it was already in use by the 11th century to denote the musical interval (although the principal name for the interval at that time seems still to have been diapason) What system was in use in medieval Europe when the term octave arose, and what did the term octave refer to? I'm a little hazy on
  • Is 16va proper notation? - Music: Practice Theory Stack Exchange
    The basis of both the frequency and the cents measurement is a 2:1 octave relationship Because pitch measurement systems (linear and logarithmic) are derived from the octave as 2:1, a double octave represented as 16va (16:8 = 2:1) is a notation evolution surpassing music theory symbols based on an outdated, extended modal scale series, like 15ma
  • Why does the scale have seven (or five) notes? Why not six?
    3 Three musical intervals are special: the octave, the perfect fifth, and the perfect fourth If one plays a note and its first three harmonics, the intervals among those pitches will be an octave, a fifth, and a fourth Scales tend to sound good if some of their notes have intervals of perfect or near-perfect fifths or fourths between them
  • Ottava markings - Should this 8va be 8vb? - Music: Practice Theory . . .
    The use by editors of 8vb rather than 8va as a notation for playing notes an octave lower than written causes octave markings below the staff to be described or pronounced differently from one above the staff
  • Simple way to add an additional octave in Musescore?
    I wrote an arrangement in Musescore, and I got complaints that some (most) notes on a particular instrument were too high for a beginner So now I want to add an additional lower octave for each no
  • theory - When was the word octave first used? - Music: Practice . . .
    So who first used the word "octave" in the modern music-theoretical sense, and, more importantly, when? By "the word 'octave'" I mean any word in any language that relates to the number eight, though I expect that it will most likely be the Latin word octava or some variant thereof
