Hameer is a nocturnal Hindustani classical raga nominally placed in Kalyan thaat.
However, some exponents consider the vaadi swar to be pancham (G natural) as Hameer is mainly sung in the upper half of an octave and is nocturnal.
As it happens, the Hindusthani raagas Kedar, Kamod and Hameer have fairly strong genetic overlap; in Kedar, madhyama is prominent; in Kamod it is Pancham; and in Hameer it is dhaivat which is most dominant.
The general ascent and descent of the notes is: Scholars do not permit the use of teevra madhyam in this raga and consider it to have emanated from Bilaval.
A special characteristic feature of this raga is the specific way in which the dhaivat (dha) is sung or played with a touch of upper nishad (ni) at the beginning.
