How to find your vocal range and correct sruti or key?

In this post, we will help you with identifying your (modal) voice register and consequently your sruti. For those of you who are not aware of these concepts, let me clarify what they actually mean.

What is Sruti?

The word Sruti is mainly used in the context of tuning, whether it is an instrument or voice. For voice, it is the frequency at which the person is most comfortable talking or singing in. For a singer, Sruti corresponds to their Shadja or ‘Sa’.

What is Voice register?

Each of our voices are different. They differ in many characteristics, one of which is the range of frequencies/pitches they produce. The differences between physical characteristics of vocal chords in men and women result in women in general producing high-pitched sounds than men. The total range of such frequencies one can produce – ranging from the deepest or lowest frequency to the shrillest or highest one – is called as voice register.

What is the link between your voice register and your Sruti?

Choosing a right sruti goes a long way in helping you sing in the broadest possible voice register in the most comfortable way. Let me break this sentence down for you, one phrase at a time.

‘.. sing in the broadest possible voice register ..’: Voice register of a singer must span at least 2 octaves. You can start identifying your vocal range by singing the lowest and highest svaras/notes you can. It is completely ok to have a vocal range of 1 octave when you begin. You will eventually expand this range by practicing different svara patterns.

‘Choosing a right sruti ..’: A svara that is half octave above the deepest/lowest note that you can sing corresponds to your sruti. This becomes Shadja or ‘Sa’ of the middle octave for your voice register. This helps you to comfortably sing the melodic patterns that span your voice register. You should also be able to sing at least one octave above your sruti.

How to increase your vocal range?

In Carnatic music, you can do this by practising Sthayi varishais/varusalu. These are svara patterns in different octaves that gradually help you in singing lower and higher svaras/notes. In Hindustani music, Kharaj ka Riyaz is serves the same purpose. You can find these vocal exercises in our Hindustani 101 course. Mornings are usually the best time to practise these vocal exercises as your voice can go deeper compared to the rest of the day. Practising lower registers in the mornings will also significantly help in your ability to practise higher registers later.

How can I find my vocal range?

Riyaz comes with “My vocal range” feature (can be found in the side menu), which will help you find your vocal range which also suggests an ideal sruti for your voice. Here is a video explaining how it works.

    Thank you for this app. It is really helping me to practice and improve my singing.
    Article is very informative for beginner like me but I am not able to understand ‘Choosing right sruti’.
    Anyways keep coming with more informative articles.

      That’s awesome to hear, Ricky! Let me try to explain the part you weren’t able to understand. Let’s say the lowest note you are able to sing is X. This X can be anything. For me, it is G2 (98 Hz). Half octave above that is D3 (146.83 Hz), which will be my Sruti. This will be my ‘Sa’ of the middle octave (madhyama sthayi).

      If you are not aware of D3/G2, look at this article on wiki –

      Hope that helps in understanding it better.

      • Ashley Ashley April 26, 2017

        How you lay out the steps how I can use this app to find my lowest note so that I can find my right Sa. I usually sing in A but I have a feeling that A# might be more comfortable for me. However going half octave above A# might be a problem.

    I am using the app to practice my scales, I have selected my Pitch as C, but I find every time I try, my voice naturally pitches a tiny little bit below C, is there some way I can adjust the setting to a shade below C, or should I train my voice to hit C perfectly?

    • Gopala Krishna Koduri Gopala Krishna Koduri Post author | April 14, 2017

      Hi Milind,
      In music classes, it is a common practise to make lessons available in frequently practised scales/srutis. And it is very common that students find themselves singing slightly above or below a chosen standard scale like C in your case. Usually, students are encouraged to sing in the provided scale as it also later becomes easier to tune instruments when you sing in a group.

      Best wishes.

    What if my lowest note is G1/G#1, what would be my scale?

    • Anil Anil June 4, 2017

      C2 /C#2 resp. Basically treat your lowest note as PA. And count PA, dh, DH, ni, NI, SA (small case = komal).

      • Arthi Arthi February 2, 2022

        Thanks it is helpful.. but actually when i start to sing my scale was in A3.. i just gradually increase my voice. but now i could comfortably sing D4 scale.. is that ok to switch other scales? Or do i have to maintain the same scale that i previously sing?

  7. Ruchi Ruchi May 30, 2017


    This app is really nice..
    Four years back I joined Hindustani music. Teacher asked me to sing A#. I practised that only but for a year, not regularly. I had problem with my throat that time ENT asked not to sing or I will lose my natural voice.
    Now, the Riyaz m trying. I can comfortably practise in A# only. But there is breathing problems where there is SaSa’ (low and high swara together).
    And other thing is when I sing, like any song, some of my friends say there is no swara, only voice. What is it? What improvement I needed.

  8. Anil Anil June 4, 2017

    Thanks for this app! It’s nicely done but useless for me as of now. I am hoping to see you will add more scales. I sing in F# (Kaali Teen, male). Can you add that asap, pleeease!

  20. Mukesh Mukesh July 4, 2020

    Riyaz App suggest my shruti key G#2, So G#2 (which is mandra saptak pa) become ‘Sa’ for me. Usually it is C#3 for male. Now i have confusion here i have to do only Riyaz of ‘Sa’ and Riyaz of alankar on this G#2 key Or what ever the song i will practice also on this key by converting its original scale to G#2. On the other hand G#2 is a low note so is this good idea to practice song on this key?

    • Mukesh Mukesh July 7, 2020

      Please advice me….the shruti key G#2 suggested by App is this okay? Or i should riyaz ‘Sa’ on higher note….I noticed my vocal range is D#2 to D#4

    This is not good app. There is no My vocal range feature in the latest version. This may be some kind of catch to make you install their app.
