Hi every I assumed this can be of attention to some on hereCopied from my website new technical article.The octave numbering man C3 C4 etc.Some thing else to think about.If you move you compositions around between different manufactures keyboards and different computer music software you will certainly soon autumn foul the the octave number is numbered night mare.I will try and make some feeling of it for you.Normal Octave notation is offered here in the worldwide Organization because that Standardization ISO system, here octave -1 (minus one) is C0 this way therefore that middle C will be C4 being the fourth C ~ above a 88 keep in mind piano.Great but:Yamaha speak to middle C = C3 why? due to the fact that they begin counting from 0 no -1This sits fine on a 61 note key-board as the is the third C from the bottom as a 61 note key-board that beginning on C1and no C0 or C-1.Ok still with me.Unfortunately every manufacturer and software music programme writers have actually their own ideas around this.For example Cakewalk Sonar contact middle C = C5 There"s no global rule, therefore it deserve to be confusing. SONAR starts counting with MIDI keep in mind 0 as C0. Girlfriend can adjust the "Base Octave because that Pitches" top top the alternatives | an international | general tab. I have actually mine in ~ -2 to enhance my Yamaha keyboard, where center C is C3...Another strange thing around Yamaha is even on a Clavinova through 88 secrets they still speak to middle C = C3 also though that is now the fourth C increase the keyboard. Quiet at least it is consistent across the range of instruments.Never psychic in truth these octave surname are just labels in this context and also do not have any kind of relationship to pitch really.in the people of digital music.As the all functions by Midi anyway and midi has to work with note numbers, the is every note, needs to have a midi number (computers can’t check out sharps and also flats from a score and interpret them prefer you can)There are two gold rules that save some sanity in all this:All MIDI gadgets use this numbers.The midi spec says that middle C shall constantly be keep in mind number 60. (No matter what you label the octave! and that A above middle C shall be tuned come 440 htz this is Midi keep in mind 69Thank goodness for that.An historical note in the early days of electronic music some bright technicians rather than musicians thought that some point as an easy as center C must work come the strength of 2This was good for digital and also put center C in ~ 256 Htz regrettably this is no the exactly frequency for center C i beg your pardon is approximately 261.6 HzTo summariseWhen the A440 pitch standard is supplied to song a music instrument, center C has actually a frequency about 261.6 Hz. Center C is designated C4 in scientific pitch notation due to the fact that of the note"s position as the fourth C vital on a conventional 88-key piano keyboardBut no Yamaha center C=C3.Another system well-known as scientific pitch assigns a frequency that 256 Hz to center C but, while numerically convenient, this is not used by orchestras. Other note-octave systems, including those offered by some makers of digital music keyboards, might refer to middle C differently. In MIDI, middle C is keep in mind number 60.The C4 designation is the most frequently recognized in auditory scientific research <>, and in musical studies it is often used in place of the Helmholtz designation c".Here space the links to printable versions connect to PDF printable versionhttps://app.box.com/s/nh31qsrn0ufuqytzf9qgwhplj8w35rd8Link come DOC printable versionhttps://app.box.com/s/4cyggwjftidsrq7t62e0mt9c1hwz0vduLink to my websitehttp://myweb.tiscali.co.uk/mikesmusic/index.htmlThanks for acquisition the time.Have funBest regards Mike Head
