In Hindustani music, there are typically seven basic notes, known as "svaras" or "swaras". These seven notes are:   1. Sa (Shadja) - equivalent to the Western note "C" 2. Re (Rishabh) - equivalent to the Western note "D" 3. Ga (Gandhar) - equivalent to the Western note "E" 4. Ma (Madhyam) - equivalent to the Western note "F" 5. Pa (Pancham) - equivalent to the Western note "G" 6. Dha (Dhaivat) - equivalent to the Western note "A" 7. Ni (Nishad) - equivalent to the Western note "B"   However, Hindustani music also employs various microtones and ornaments, known as "shrutis", which can be thought of as intermediate notes between the seven basic svaras. These shrutis add richness and depth to the music.   In total, Hindustani music recognizes 22 shrutis, which are used to create a wide range of emotional expressions and nuances in the music.
