To free up your voice, simply breathe in, and then as you breathe out perform a vocalised sigh. You'll notice this sounds like a pitch sweeping downwards, but it will probably feel more natural than regular singing exercises. Try and make your sigh as vocalised as possible so it's close to actually singing.
In music, intonation is the pitch accuracy of a musician or musical instrument. Intonation may be flat, sharp, or both, successively or simultaneously. In vocal music, intonation also signifies the singing of an opening phrase.
Because the intonation choices that the vocal ensemble singer faces are quite complex, work on intonation issues is central to vocal ensemble practice, not only in terms of exact pitches, but also concerning aspects of voice technique, communication between singers and the balancing of voices.
Meanwhile, an orchestra is made of a bunch of instruments, some of which tune naturally by ear—strings, woodwinds, brass—but also instruments in fixed, equal temperament: harp, marimbas and xylophones, harpsichord and piano, etc.
In music, intonation refers to pitch accuracy - that is, whether a tone is played 'in tune' or not. In order to play or sing in tune with proper intonation, it is vitally important to have a keen sense of pitch differentiation.
Tune all the open strings to what you want to set them to at the 12th fret harmonic. Now fret those strings at the 12th fret. If they're sharp or flat, the intonation has to be adjusted. This is done by moving the bridge saddles either forward or backward depending if those fretted notes are sharp or flat.
Just intonation frequencies are based on the harmonic series. However, if an instrument is tuned with the frequencies obtained in the above manner, the instrument only sounds good in one key. In other keys it sounds out of tune (because the frequency ratios for the intervals are not simple integer fractions like 3/2).
Just tuning is often used by ensembles (such as for choral or orchestra works) as the players match pitch with each other "by ear." The "equal tempered scale" was developed for keyboard instruments, such as the piano, so that they could be played equally well (or badly) in any key.
The
cent is a logarithmic unit of measure used for musical intervals. Twelve-tone equal temperament divides the octave into 12 semitones of 100
cents each.
Centitone.

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.
In music theory, a perfect fifth is the musical interval corresponding to a pair of pitches with a frequency ratio of 3:2, or very nearly so. The perfect fifth (often abbreviated P5) spans seven semitones, while the diminished fifth spans six and the augmented fifth spans eight semitones.
Supposedly used in medieval monophonic music (melody only, without harmony) and considerably discussed by theorists, just intonation proved impractical for polyphonic (multipart) music and was replaced at least by the year 1500 by meantone temperament.
In equal temperament, pairs of enharmonic notes such as A♭ and G♯ are thought of as being exactly the same note—however, as the above table indicates, in Pythagorean tuning they have different ratios with respect to D, which means they are at a different frequency.
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. All…
In music, just intonation or pure intonation is the tuning of musical intervals as whole number ratios (such as 3:2 or 4:3) of frequencies. Any interval tuned in this way is called a just interval.
From a C, we will build a major scale according to the Pythagorean tuning. We first calculate the fifth by multiplying the frequency of C by 3/2 (fifth size): To multiply a number by a fraction we multiply by the numerator (top number) and then divide by the denominator (bottom number). G = 261 x 3 / 2.
Pythagoras observed several ratios of sound wave frequencies and the corresponding intervals between them, including 4:3 (known to musicians as the interval of a perfect fourth, or two pitches that are five semitones apart from each other) and 3:2 (a perfect fifth, seven semitones apart).
Pythagoras believed that the planets themselves, all heavenly bodies, rang out notes of vibration based on their orbit and distance to each other. We humans simply lack the ability to hear this music of the spheres. These mathematical ratios helped to define every system of intonation throughout history.
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.
A semitone (sometimes called a half tone or a half step) is the distance from a white key to a neighboring black key on the piano keyboard—for example, from G to G-sharp or from E to E-flat. Semitones are the smallest intervals that are used intentionally in almost any of the music you'll normally hear.
Short definition for those who just want to play: (go to technical definition) The Justonic system allows fixed tone or fretted instruments (keyboards and guitars) to play pure harmonic music which requires that all notes must be flexible, and they must be precisely retuned, on the fly, in real-time as you play.
