Understanding just intonation, Timidity, and Scala?



Asked by: Kelli Chika

How do you explain just intonation?





just intonation, in music, system of tuning in which the correct size of all the intervals of the scale is calculated by different additions and subtractions of pure natural thirds and fifths (the intervals that occur between the fourth and fifth, and second and third tones, respectively, of the natural harmonic series

What is the difference between just intonation and equal temperament?

Just Intonation: smooth chords, melody notes that sound out of tune. 2. Equal Temperament – melody notes sound in tune, chords sound rough. One of the best ways to understand the difference Equal Temperament and Just Intonation is to play harmonicas tuned to JI and ET and compare the way they sound.

Who invented just intonation?

Harry Partch was the first such composer. He defined his own scale with 43 pitches to the octave, and invented his own instruments to play it.

What is the difference in cents between the interval of a major 3rd m3 in just intonation vs in equal temperament?

In an equal tempered tuning, a minor third is equal to three semitones, a ratio of 21/4:1 (about 1.189), or 300 cents, 15.64 cents narrower than the 6:5 ratio.



Minor third.

Name
Just intonation 316, 298, 294

Why does just intonation sound better?





Our brains tell us that the first interval is more consonant, simply because it requires less effort to process than the second one. Of course, in the real world, things are rarely absolutely perfect and two tones in the ratio of 40001:50001 will be heard as “near enough” to 4:5.

How do I tune in just intonation?

For example the minor second of any note is a note one semitone higher the major second of any note is the note two semitones higher etc.

Is just intonation the same as Pythagorean?

Pythagorean tuning provides uniformity but not the chords. Just tuning, based on the simpler ratios of the overtone series, provides the chords but suffers from inequality of intervals. Meantone tuning provides equal intervals but gives rise to several objectionable chords, even in simple music.

Are guitar frets equal temperament?

Guitars are tuned to ‘equal temperament’. The basic way to understand this is that the 12 musical notes are evenly split up, which allows us to use straight frets on a guitar. The problem is that equal temperament isn’t perfect and depending on how you have trained your ears, you may notice it when you play guitar.

How many notes are in just intonation?

To produce a twelve-tone scale, one of them is arbitrarily discarded. The twelve remaining notes are repeated by increasing or decreasing their frequencies by a power of 2 (the size of one or more octaves) to build scales with multiple octaves (such as the keyboard of a piano).



What is wrong with just intonation?

An ideal system (for Western people) would be based on the natural harmonic series, because we love how harmonics sound. This kind of tuning system is called just intonation. It sounds lovely! Unfortunately, just intonation makes it impossible to change keys or tune your guitar.

What is the main problem with the just scale?

All the notes in the scale are related by rational numbers. Unfortunately, with Just tuning, the tuning depends on the scale you are using – the tuning for C Major is not the same as for D Major, for example.

Is the harmonic series in just intonation?

It states that just intonation is a method of tuning based on the intervals of the harmonic series. In the West, some of the oldest extant sources that give detailed accounts of rational or integer number ratios in music are the Division of the Canon by Euclid (fl.



Is just intonation microtonal?

just intonation – microtonal musical tuning system and scale.

What is 5 limit just intonation?

Five-limit tuning



The 5-limit consists of all just intonation intervals whose numerators and denominators are both products of the primes 2, 3, and 5; these are sometimes called regular numbers. Some examples of 5-limit intervals are 5/4, 6/5, 10/9 and 81/80.
