The threefold amalgamation of vocal music (gayaki), instrumental music (vadhya sangeet) and dance or gesticulation (nritya).
Two major systems of music - Uttari or Hindustani and Dakshini or Carnatic.
Everything we hear is a dhvani. Some are peaceful to hear, and are called Naad.
Back and forth vibrating movement of the strings of musical instruments is called Aandolan or Kampan. Aandolan leads to generation of Dhvani.
Sweet dhvanis created by proper, stable vibrations, that are fit to be used in sangeet.
There are three characteristics of Naad:
Infinite naad in a saptak, ie Sa to Ni, but ancient scholars estimated there to be at most 22 naad that the human ear could detect and a singer or musical instrument could produce.
Some scientific evidence shows that the number of perceptible intermediate tones may be less or more than 22. The phenomenon of intermediate tones is pursued as an active area of research in Indian Musicology.
12 prominent shrutis out of the 22.
Shadaj, Rishabh, Gandhar, Madhyam, Pancham, Dhaivat, Nishad, or simply as they're most commonly known, Sa, Re, Ga, Ma, Pa, Dha, Ni (Sargam).
Similar to sol-fa of western music, ie Do, Re, Mi, Fa, So, La, Ti
Two types: Shuddh (Pure) or Vikrit (Distorted)
Vikrit: Komal (Flat) or Teevra (Sharp)
Chal svar: Re, Ga, Ma, Dha & Ni
Achal svar: Immutably fixed - Shadaj and Pancham
Svaras are assembled to make scales, called saptak ("containing seven"). Frequency of svaras increases as we progress along the sequence.
The 7 shuddh notes repeat in the upper and lower direction. After Nishad, Shadaj of the next octave is encountered.
Specification as to which of the 12 svaras will be chosen to create a sequence of exactly 7 major svaras, from which Ragas are generated.
A Thaat isn't performed like a Raga in classical music. It doesn't have Vadi-Samvadi, Pakad, Aalap-Taan etc. It can just lead to the generation of Ragas.
The permutations of the various alternate forms of svaras give rise to numerous scales. A thaat is analogous to the western concept of "mode".
Array of melodic structures and characteristics for improvisation according to specific rules.
Considered to have the ability to affect the emotions of the audience.
Every raga has a base, aadhar svara, that is Shadaj, or Sa. It should also have an adhista svara, either Madhyam or Pancham, that divides the saptak into two parts:
Poorvang, which contains lower notes, and Uttarang, which contains the hight notes.
Not all svaras are always used in a raga. For example in Bhopali, Madhyam and Dhaivat are not played. These are called Vyarja svaras.
In addition to the main characteristics of raga, there are some other less followed ones.
For instance, ragas have traditionally been attributed to particular times of the day.
Ragas with the Vadi falling in the lower half of the Saptak are called Poorvang Pradhan Ragas, and those with the Vadi in the upper half or Uttarang of the Saptak are called Uttarang Pradhan Ragas.
Poorvang Ragas are performed from midnight to 12 noon, whereas Uttarang Ragas are performed from 12 pm to midnight.
Initial section of the Raga, where its svaras are played in vilambit laya.
Most prominent section for showing fine features like meend, kan, khatka, murki, gamak etc.
Gat or Bandish is a fixed melodic composition in the svaras of the specific raga, set to rhythm.
The initial phrase of the Gat is called Sthayi. The first body or block is called the Antara.
Improvisation of very rapid melodic passages.
A phrase that is played 3 times, usually to conclude a taan or section.
Sometimes used to distort the listeners' perception of time, only to reveal the consistent underlying cycle at the sam.
Fast-paced conclusion of the raga.
Taal is the Indian system of rhythm. Rhythm existed many centuries before the word raga was ever used.
