The musical interval of a ditone is literally two tones, whole tones or major seconds, often called a major third. In contrast to a major third, ideally a just 4:5 or 4 equally tempered semitones, however, a ditone is ideally a pythagorean 64:81 = 1.2656 = 1.1252 = 9:82, two 9:8 whole tones. In music theory, an interval is the difference (a ratio or logarithmic measure) in pitch between two notes and often refers to those two notes themselves (otherwise known as a dyad). ... The musical interval of a major second — also called a whole-tone — is the relationship between the first note (the root or tonic) and the second note in a major scale (and also a minor scale). ... The musical interval of a Major third is the relationship between the first note (the root or tonic) and the third note in a major scale. ... Equal temperament is a scheme of musical tuning in which the octave is divided into a series of equal steps (equal frequency ratios). ...
Contrast with: Major third, Ditonus, two major seconds or whole tones In harmony, the ditonus (Latin for double tone — plural ditoni) is the ratio 5:4 (sesquiquartum) between a pair of frequencies or, equivalently, the ratio 4:5 between a pair of wavelengths. ...
This has the ratio 9/8, and it is the only other superparticular ratio of Pythagorean tuning, as shown by Størmer's theorem.
The ditone differs from the just major third (5/4) by the syntonic comma (81/80).
Likewise, the difference between the tone and the perfect fourth is the semiditone, a narrow minor third, 32/27, which differs from 6/5 by the syntonic comma.
Ditone is the sole UK company and one of only three worldwide, to recently acquire new world-class plate making technology by Dupont which increases processing speeds by 50 per cent and improves print quality even further.
Ditone Labels can offer a variety of print processes for both long and short runs, including flexo and UV flexo, rotary and semi-rotary letterpress, as well as in-line screen, foil blocking and variable information printing, and the company has additional state-of-the-art presses on order.
Ditone Labels, which has a turnover in excess of £6M and a staff of 70 people, was acquired by printing and packaging products specialist Clondalkin in 1991, and became part of The Boxes Group in 1997.
