Fret Science Understand More. Memorize Less.

Play guitar solos effortlessly—without endless memorization

Are you an intermediate guitarist who’s frustrated by memorizing scales, overwhelmed by music theory, and struggling to put it all together when improvising?

Fret Science was built for you.

Improv 101 is here!

Why Fret Science Works

Hi, I’m Keith Martin. For over 30 years, I struggled with improvisation and felt trapped by endless memorization. It wasn’t until I applied my computer science background (MIT Ph.D. plus a 25-year career as a research engineer) to guitar that everything clicked. Within weeks, I went from confusion to clarity, from frustration to freedom.

Now, guitarists around the world—from beginners to highly advanced players—are experiencing rapid breakthroughs using the Fret Science method.
