35-528: A thaat ( IAST : thāṭ ) is a "parent scale " in North Indian or Hindustani music . It is the Hindustani equivalent of the term Melakartha raga of Carnatic music . The concept of the thaat is not exactly equivalent to the western musical scale because the primary function of a thaat is not as a tool for music composition, but rather as a basis for classification of ragas . There

The modern thaat system was created by Vishnu Narayan Bhatkhande (1860–1936), an influential musicologist in the field of classical music in the early decades of the twentieth century. Bhatkhande modelled his system after the Carnatic melakarta classification, devised around 1640 by the musicologist Vidwan Venkatamakhin . Bhatkhande visited many of

One letter has a line below: ḻ ( / ɭ / ) (Vedic). Unlike ASCII -only romanisations such as ITRANS or Harvard-Kyoto , the diacritics used for IAST allow capitalisation of proper names. The capital variants of letters never occurring word-initially ( Ṇ Ṅ Ñ Ṝ Ḹ ) are useful only when writing in all-caps and in Pāṇini contexts for which

These chords may also appear as seventh chords : in major, as I , or in minor as i or rarely i : The tonic is distinguished from the root , which is the reference note of a chord, rather than that of the scale.

By contrast, the ISO 15919 standard for transliterating Indic scripts emerged in 2001 from the standards and library worlds.

245-536: A good idea to have the term 'tone center' refer to the more general class of which 'tonics' (or tone centers in tonal contexts) could be regarded as a subclass." Thus, a pitch center may function referentially or contextually in an atonal context, often acting as an axis or line of symmetry in an interval cycle . The term pitch centricity was coined by Arthur Berger in his "Problems of Pitch Organization in Stravinsky". According to Walter Piston , "the idea of
280-526: A piece are hierarchically referenced. Scales are named after their tonics: for instance, the tonic of the C major scale is the note C . The triad formed on the tonic note, the tonic chord , is thus the most significant chord in these styles of music. In Roman numeral analysis , the tonic chord is typically symbolized by the Roman numeral "I" if it is major and by "i" if it is minor. In very much conventionally tonal music, harmonic analysis will reveal
315-410: A rough structure of the raga and do not give an idea of how the raga should be sung. It is pakad of the raga that gives the chalan or way of singing of the raga. Bhatkhande named his thaats after the prominent ragas associated with those thaats. Ragas on which the thaats are named are called Janak raga of that thaat. For example, Bilaval Thaat is named after the raga Alhaiya Bilaval. Alhaiya Bilaval raga
350-476: Is C. However, relative keys (two different scales that share a key signature ) have different tonics. For example, C major and A minor share a key signature that feature no sharps or flats, despite having different tonic pitches (C and A, respectively). The term tonic may be reserved exclusively for use in tonal contexts while tonal center or pitch center may be used in post-tonal and atonal music: "For purposes of non-tonal centric music, it might be

The ten thaats are Bilawal, Kalyan, Khamaj, Bhairav, Poorvi, Marwa, Kafi, Asavari, Bhairavi and Todi; if one were to pick a raga at random, in theory it should be possible to classify it into one of these thaats. For instance, the ragas Shree and Puriya Dhanashree are based on the Poorvi thaats, Malkauns on the Bhairavi thaat, and Darbari Kanada on

455-421: Is not necessarily strict compliance between a raga and its parent thaat ; a raga said to 'belong' to a certain thaat need not allow all the notes of the thaat , and might allow other notes. Thaats are generally accepted to be heptatonic by definition. The term thaat is also used to refer to the frets of stringed instruments like the sitar and the veena . It is also used to denote the posture adopted by
490-427: Is represented by a letter followed by a single quote (i.e. M'). The upper octave is italicized. There are many ragas that do not fall in the thaat system. Some ragas have been derived from Carnatic music and hence do not fall in the Hindustani classical thaat system. Some of them are: 1. Kirvani 2. Nat Bhairav 3. Charukeshi 4. Madhuvanti 5. Ahir Bhairav Ragas are normally ascribed to certain periods of

The thaats are listed here according to their pitches. Lower pitches ( komal or flat) are represented with lowercase letters and natural pitches ( shuddha or natural) with uppercase letters. A raised pitch ( tivra or sharp)
560-405: The common practice period , the tonic center was the most important of all the different tone centers which a composer used in a piece of music, with most pieces beginning and ending on the tonic, usually modulating to the dominant (the fifth scale degree above the tonic, or the fourth below it) in between. Two parallel keys have the same tonic. For example, in both C major and C minor, the tonic
595-405: The gharanas (schools) of classical music, conducting a detailed analysis of ragas . His research led him to a system of thirty-two thaats, each named after a prominent raga associated with it. Out of those thirty-two thaats, more than a dozen thaats were popular during his time; however, he chose to highlight only ten such thaats. According to Bhatkhande, each one of the several traditional ragas
630-439: The tonic is the first scale degree ( [REDACTED] ) of the diatonic scale (the first note of a scale) and the tonal center or final resolution tone that is commonly used in the final cadence in tonal (musical key -based) classical music , popular music , and traditional music . In the movable do solfège system, the tonic note is sung as do . More generally, the tonic is the note upon which all other notes of

The seven basic swaras of the scale are named shadja, rishabh, gandhar, madhyam, pancham, dhaivat and nishad , and are abbreviated to Sa, Ri (Carnatic) or Re (Hindustani), Ga, Ma, Pa, Dha, and Ni and written S, R, G, M, P, D, N. Collectively these notes are known as the sargam (the word is an acronym of the consonants of

It is this faithfulness to the original scripts that accounts for its continuing popularity amongst scholars. Scholars commonly use IAST in publications that cite textual material in Sanskrit, Pāḷi and other classical Indian languages. IAST is also used for major e-text repositories such as SARIT, Muktabodha, GRETIL, and sanskritdocuments.org. The IAST scheme represents more than

Selecting seven tones in ascending order, where S and P are always natural whereas five other tones (R, G, M, D, N) can assume only one of its two possible forms, results in 2 = 32 possible modes which are known as thaats . Out of these thirty-two possibilities, Bhatkhande chose to highlight only ten thaats prominent in his days. In effect only heptatonic scales are called thaats . Bhatkhande applied

875-422: The day and night ( See Samayā ). Narada 's Sangita-Makaranda , written sometime between the 7th and 11th century, gives warnings to musicians against playing ragas at the incorrect time of day. Traditionally, disastrous consequences are to be expected. Bhatkhande claimed that the correct time to play a raga had a relation to its thaat (and to its vadi ). However, the author of Nai Vaigyanik Paddhati says that
910-642: The degree of fit between a raga and its thaat is balanced with the desire to keep the number of basic thaats small. Ambiguities inevitably arise. For example, Raga Hindol, assigned to Kalyan thaat, uses the notes S G M D N, which are also found in Marwa thaat. Jaijaiwanti contains both shuddha Ni and komal Ni (and sometimes both versions of Ga as well), which by definition corresponds to no thaat. Bhatkande resolved such cases "by an ad hoc consideration, appealing to musical performance practice" (see Ramesh Gangolli's article, cited in note 4 above). Note that thaats only give
945-741: The first four swaras ). Sargam is the Indian equivalent to solfège , a technique for the teaching of sight-singing. The tone Sa is not associated with any particular pitch. As in Western moveable solfège, Sa refers to the tonic of a piece or scale rather than to any particular pitch. In Bhatkhande's system, the basic mode of reference is that which is equivalent to the Western Ionian mode or major scale (called Bilawal thaat in Hindustani music, Dheerasankarabharanam in Carnatic). The flattening or sharpening of pitches always occurs with reference to

1155-535: The term thaats only to scales that fulfil the following rules: One can arbitrarily designate any pitch as Sa (the tonic ) and build the series from there. While all thaats contain seven notes, many ragas (of the audav and shadav type) contain fewer than seven and some use more. A raga need not to use every tone in a given thaat; the assignment is made according to whatever notes the raga does contain (but see note 5). The relatively small number of thaats reflects Bhatkhande's compromise between accuracy and efficiency:
