Śruti (music)
The ''shruti'' or ''śruti'' is the smallest interval of pitch that the human ear can detect and a singer or musical instrument can produce. The concept is found in ancient and medieval Sanskrit texts such as the ''Natya Shastra'', the '' Dattilam'', the ''Brihaddeshi'', and the ''Sangita Ratnakara''. ''Chandogya Upanishad'' speaks of the division of the octave in 22 parts. The ''swara'' differs from the ''shruti'': the ''shruti'' is the smallest gradation of pitch available, while a ''swara'' is the selected pitches from which the musician constructs the scales, melodies and ''ragas''. The ''Natya Shastra'' identifies and discusses twenty two ''shruti'' and seven ''swara'' per octave. It has been used in several contexts throughout the history of Indian music. Recent research has more precisely defined the term ''shruti'', its difference from ''nada'' and ''swara'', and identified positions on a string to play 22 shrutis. The most well-known example of shrutis is pr ...

Divine Music
Divinity (from Latin ) refers to the quality, presence, or nature of that which is divine—a term that, before the rise of monotheism, evoked a broad and dynamic field of sacred power. In the Classical antiquity, ancient world, divinity was not limited to a single deity or abstract ideal but was recognized in multiple forms: as a Divine radiance, radiant attribute possessed by gods, as a vital force pervading nature, and even as a quality glimpsed in extraordinary humans, laws, or acts. The Latin and its Greek counterparts (, ) conveyed something both immanent and awe-inspiring: a presence that could be felt in List of thunder deities#Greco-Roman, thunder, Dike (mythology), justice, Ecstasy (emotion), ecstasy, Moirai, fate, or List of beauty deities#Greek, beauty. Among the Ancient Greece, Greeks and Ancient Rome, Romans, divinity was not confined to a rigid theological system. Gods, heroes, and even emperors might be described as partaking in divinity, just as natural forces o ...

Dattila
Dattilam (दत्तिलम्) is an ancient Indian musical text ascribed to the sage (muni) Dattila. It is believed to have been composed shortly after the Natya Shastra of Bharata, and is dated between the 1st and 4th century AD. But Bharathamuni had given reference of the treatise " Dattilam" in his celebrated work "Natyashastra"(1-26) so there is a belief that Dattilam may be a work composed before Bharata Muni. Written in 244 verses, Dattilam claims to be a synthesis of earlier works on music. The text marks the transition from the '' sama-gayan'' (ritual chants as in the Samaveda), to what is known as gandharva music, after the gandharvas, musically adept spirits who are first mentioned in the Mahabharata. Dattilam discusses scales (swara), the base note (''sthana''), and defines a tonal framework called ''grama'' in terms of 22 micro-tonal intervals (''sruti'') comprising one octave. It also discusses various arrangements of the notes (''murchhana''), the permuta ...

Syntonic Comma
In music theory Music theory is the study of theoretical frameworks for understanding the practices and possibilities of music. ''The Oxford Companion to Music'' describes three interrelated uses of the term "music theory": The first is the "Elements of music, ..., the syntonic comma, also known as the chromatic diesis, the Didymean comma, the Ptolemy, Ptolemaic comma, or the diatonic comma is a small Comma (music), comma type interval (music), interval between two musical notes, equal to the frequency ratio (= 1.0125) (around 21.51 cent (music), cents). Two notes that differ by this interval would sound different from each other even to untrained ears, but would be close enough that they would be more likely interpreted as out-of-tune versions of the same note than as different notes. The comma is also referred to as a ''Didymean comma'' because it is the amount by which Didymus the Musician, Didymus corrected the Pythagorean interval, Pythagorean major thir ...

Just Chromatic Semitone
A semitone, also called a minor second, half step, or a half tone, is the smallest musical interval commonly used in Western tonal music, and it is considered the most dissonant when sounded harmonically. It is defined as the interval between two adjacent notes in a 12-tone scale (or half of a whole step), visually seen on a keyboard as the distance between two keys that are adjacent to each other. For example, C is adjacent to C; the interval between them is a semitone. In a 12-note approximately equally divided scale, any interval can be defined in terms of an appropriate number of semitones (e.g. a whole tone or major second is 2 semitones wide, a major third 4 semitones, and a perfect fifth 7 semitones). In music theory, a distinction is made between a diatonic semitone, or minor second (an interval encompassing two different staff positions, e.g. from C to D) and a chromatic semitone or augmented unison (an interval between two notes at the same staff position, e.g. from ...

53 Equal Temperament
In music, 53 equal temperament, called 53 TET, 53  EDO, or 53 ET, is the tempered scale derived by dividing the octave into 53 equal steps (equal frequency ratios) (). Each step represents a frequency ratio of or 22.6415  cents (), an interval sometimes called the Holdrian comma. 53 TET is a tuning of equal temperament in which the tempered perfect fifth is 701.89 cents wide, as shown in Figure 1, and sequential pitches are separated by 22.642 cents. The 53-TET tuning equates to the unison, or ''tempers out'', the intervals known as the schisma, and known as the kleisma. These are both 5 limit intervals, involving only the primes 2, 3, and 5 in their factorization, and the fact that 53 TET tempers out both characterizes it completely as a 5 limit temperament: It is the only regular temperament tempering out both of these intervals, or commas, a fact which seems to have first been recognized by Japanese musi ...
