In this lesson, we will discuss about saptak/octaves in music. In prev lesson, we learnt about 12 notes and their sequence. In this lesson, we will learn about the 3 main octaves in music. There are primarily 3 octaves in music: Mandra Saptak (lower octave) Madhya Saptak (middle octave) Taar Saptak (higher octave) In simple terms to understand these three octaves. The normal voice that one usually talks in is in Mandra Saptak (lower octave). But if we want to speak something quietly in a lower voice, then it is in a lower octave (Mandra Saptak). Now if we want to call somebody who is at a distance, we will have to raise our voice. The voice gets thinner and comes out with energy. This is Taar saptak (higher octave). The 12 notes sequence that we learnt, if we combine them in the lower, middle, and higher octave, then we will be able to see how these 3 octaves are joint and can be traversed. Also, if we go below mandra saptak, it is called ati-mandra saptak. And if go above taar saptak, it is called ati-taar saptak. You might have seen large pianos having a large number of octaves, however, for vocal practice, we normally sing and practice in three main octaves. If one can build his/her range from mandra saptak pancham to taar saptak pancham, then it is more than enough in the beginning stage. Our Sa is madhyam saptak Sa. Watch the video for the demonstration of three octaves. We will discuss about these octaves and notes, in the coming lessons.
