- 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?
- Why do clef octave changes use 8 and 15? [duplicate]
Here, there's a series of octave clefs listed as using 8 and 15 to alter the clef by one or two octaves respectively My understanding of music theory is that there are 12 notes in an octave, and only 7 whole notes in a typical scale
- 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
- theory - What makes an interval Perfect? - Music: Practice Theory . . .
The fifth divides the octave with a fourth remaining above The fourth divides the octave with a fifth remaining above That is to complete the octave Playing Perfect intervals that suggest no harmonic content and adding harmonic content is a'sound' approach to discovering the answer to the perfect interval question All answers have certain
- 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?
Click first note and Shift + Click last note of desired selection, rests at the end of the selection don't need to be in there because they won't be affected by the octave change Ctrl + Down arrow, This lowers the existing music by an octave, so you get your lower octave for free But now you need back the upper octave Alt + 8, This adds an octave interval above the notes in the selection
- 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
