I always enjoy discovering new ways to improve my musical skills. While there are many tools out there, here’s a recent discovery that’s full of potential. If you’re looking for a convenient service to learn guitar without paying for expensive lessons, you’ve got to check this out!
JamStar is its name and is available to use from a desktop browser or mobile device (Android and iOS apps available).
Just tune your guitar (JamStar has a built-in tuner too), open a free account and start learning.
How it WorksThe app uses the microphone of a PC or mobile device to listen to your playing and give you feedback, real time. You can use a regular acoustic or classical guitar. To use an electric guitar, connect it to your amp and make sure the amp faces the microphone, that’s about it.
