432 Hz, 963 Hz, 396 Hz. Melyek még az ajánlott frekvenciák (ezen a vonalon)?

Tessék, itt megtalálod:

De pl. a hangtálak is a jó frekvenciákon mozognak, ezért érdemes használni őket!

Úgy nevezik, hogy "factor 9 grid".

Factor 9 grid is a type of musical scale which was first proposed for esoteric reasons as a supposed replacement to 12edo. The scale also became notable in music theory when esoteric properties of the scale were subsequently refuted by the famous YouTuber, bassist, and composer Adam Neely.

Theory

The scale is an isoharmonic sequence that consists of the following notes, in Hertz: 126, 135, 144, 153, 162, 171, 180, 189, 198, 207, 216, 225, 234, 243, (octave), and their octave displacements. Therefore this is an otonal scale running from 14th to 28th harmonic.This is an arithmetic progression with the difference of 9, hence why this scale was named, although quite misnomerly, "Factor 9 grid". Since the largest prime is 23, this makes Factor 9 grid a part of 23-limit just intonation.

The scale, as proposed in the video, contains a major inconsistency - it has 13 notes (G sharp and A flat are not enharmonic), while it claims to be supposedly a better replacement towards the current 12-note system and makes references towards the sacrality of the number 12. Also, the scale in the video skips number 243 for an unknown reason, given that 126 = 9 × 14, and you need 14 notes to count to the octave displacement, if you are using an arithmetic difference of 9. This page will consider the full 14:15:…:28 otonal sequence.

Since the esoteric affliction towards the note A being 432 Hz is usually considered, the scale is supposed to be played starting with A, which leaves a wide semitone inside the octave.
