Equal temperament finder - effectively finding temperament fits the all consonants

 This program finds a suitable number of equal temperaments for a series of notes or ratios. It is useful for inharmonic tuning, a more accurate and way more effective way to find the number in the previous calculation.

Separate individual items with a space bar. There are two ways to use this program: 1, enter the frequencies (Hz) from tonic to the octave; 

An example of entering an inharmonic scale in frequency:

    220  259.2   302.5   329.6296296   362.3290203   432.8

(The inharmonic pattern of a bar percussion.)

2, enter the ratio of every note relates to the tonic form to the octave

An example of entering a major scale in ratios (just intonation):

    1 1.12246 1.25992 1.33483 1.49831 1.68179 1.88775 2

The boundary of matching frequency is +/-15 cents which is an average number of comparing 12-TET and just intonation. Can be changed on lines 7 and 9.

The upper limit of finding the ET is 40, it can be changed on line 15.

The default harmonic pattern is based on harmonic series (f,2f,3f,4f,5f,6f,7f) and sound pressure level in decibel (dBSPL) corresponds to harmonics 60, 50, 40, 40, 30, 30, 30 dBSPL respectively. You can customize the parameters in the code for inharmonic instruments like percussion, and wind. The dissonant curve drawing is based on the resolution of x-asis 2^1/120for two octaves, 2^240/120, 120 steps in an octave, 240 steps in total. The function as f(x)= 2(x/120). The series as xn-1 = 2^[(xn-1)/120] , 0n-1240. It is also changeable at lines 12 and 13.

Post-spectralism influence on tuning

According to Helmholtz (2011), a musical note is due to the fundamental frequency and the quality of a musical sound is due to the presence of upper partials. For traditional western music, pitch perception is mainly fundamental, rather than the frequencies in the spectrum which Teodorescu-Ciocanea (2003) describes as a “note proper” tradition. The spectralism composers shifted the domain from absolute pitches, intervals and chords to the spectrum. Spectral music is a complex approach to timbre, Teodorescu-Ciocanea (2003) classified 9 tendencies and their possibilities in spectral music. To conclude the techniques, tuning the frequencies according to the harmonic series is the major approach; while working with noise, generated digitally and/or extended techniques on instruments, is a sort of timbral dissonance which dilutes the pitch perception of a musical sound. Teodorescu-Ciocanea describes inharmonicity as the combination of frequencies that are not integral multiples of the funda

Haba's field shifting - and the expansion of traditional functional harmony

Image
Hába characterizes the quarter-tone gamut as separated into two fields, one half comprising the twelve conventional pitches, and the other half, shifting all the twelve notes by a quarter-tone, the twelve quarter-tone pitches. In harmony, Passages occur in which chords composed purely of conventional pitches alternate with chords composed purely of quarter-tone pitches. Two fields are not always rejecting each other when he equally divided a perfect 4th (5 semitones)into 2 equal intervals, equal 2.5 for each, the 0.5 quartertones always step into the other field. Sometimes, this fourth interval can be further divided into 2.5+2+0.5 or other permutations. This kind of splitting a fourth can be traced to ancient greek tetrachord, a scale of four notes, bounded by the interval of a perfect fourth. A chord across both fields, the chord spell like a flatter dominant 7th chord. the 7th harmonic on harmonic series is quite flat (-31cents). This chord combines both fields sounds better accordi

Temperament, Tuning, and Timbre -- the underrated trinity in music

 The trinity here is not about the Christianity faith, but similar to the idea of the Christian doctrine of it defines God as being one God existing in three coequal, the core and fundamental definition, temperament, tuning, and timbre (TTT) are the basic building blocks of music, yet, underrated and even neglected in our music education system. TTT correlates with each other. A note is played, it carries out a series of frequencies, the harmonic series. The series multiples from the fundamental frequency with a series of integers (1f 2f 3f 4f 5f 6f 7f 8f 9f 10f 11f 12f 13f...). The loudness of individual particles, and different patterns, creates different timbres. View the series in a different way, the combination of the integers creates intervals. The combination of the beginning of the series sounds more harmonious and vice versa; simple ratios sound pure and vice versa. The pure perfect 5th interval is based on the ratio of 2:3 (2nd and 3rd harmonics at the same time), Pytheogoro
