It’s really interesting to see.

Can a similar thing be done with other musical instruments, singing or simply recording everyday sounds like the sound of a scooter or a car starting? @NAVTEJ7939 @Abhinav7996 @HariSharanKalia @Gurkiratsingh8013 @SINGHATAMBIR @raman8026sskp @arush @Siddharth7950 @Kamboj

The app also has an interesting thing that it can show us the notes that I am playing at the moment.
