“Whether I go to learn a song myself or teach someone how to play a song, I bring it up in Capo.”Read about Capo's use in Education ›
Capo is a fantastic way to analyze & learn music quickly; I love how clean the pitch algorithm is even at 1/4 speed. Capo is a great teaching & learning tool whether you're a rank beginner or a seasoned professional.
I have been wishing for this software for years. It's incredibly useful, whether I'm charting my own songs for the players who join me, or discovering exactly what is being played on a recording I love.
I am a devout Capo user for a couple of years now—it's the GREATEST of all, especially since it makes a library of your tunes you work on and is sonically great. It's my go-to music learning app!
Capo is an invaluable learning tool. I use it to loop hard phrases, and slow them down with very few artifacts, making them easy to master!
