What this online sur detector helps you do
A sur detector is useful when you do not need a full lesson flow yet. You just need one clean target note, live pitch feedback, and a quick answer to the question: am I centered on the swara or not?
This page strips the experience down to that core loop. Pick a swara, adjust the scale if needed, sing into your mic, and watch the feedback settle.
Three simple steps
1. Pick the swara
Choose Sa, Re, Ga, Ma, Pa, Dha, or Ni and let the tool play the reference tone for you.
2. Match your tonic
Use transpose and octave controls until the target note feels natural for your voice.
3. Hold the note steady
Sing into the mic and use the tuner to correct sharp or flat drift before moving into longer riyaz.
Best times to use this page
Use it before your main practice when you want to confirm your tonic quickly. It also works well for repeat-note stability, short sur drills, and teacher-led exercises where the note target keeps changing.
When you want more structure, switch to Sargam Practice Online for guided note progression, alankar drills, and a fuller riyaz routine.
Online Sur Detector FAQs
Common questions about using this pitch monitor for Indian classical practice.
What is an online sur detector?
An online sur detector listens to your voice through the microphone, compares the pitch against a musical target, and shows whether you are singing in tune, flat, or sharp.
Do I need a tanpura or harmonium to use this page?
No. This page can be used by itself. You can still play the reference swara from the tool and then sing it back without any external instrument.
Can I change the tonic before singing?
Yes. Use the transpose controls to move the target note until Sa sits comfortably in your vocal range.
What should I use after this page?
If you want longer guided training, move into Sargam Practice Online for note-by-note drills, alankar work, drone support, and a fuller riyaz flow.
Need the full riyaz flow?
Move into guided Sargam practice with drone support, alankar work, and session-style vocal training.
Need a harmonium simulator?
Open the virtual harmonium when you want direct keyboard practice alongside your pitch work.
Need note basics first?
Review the main harmonium notes so your ear training connects cleanly to Sa Re Ga Ma thinking.
