Is there a specific lesson or tutorial you are referring to?

For reference: https://en.wikipedia.org/wiki/Muscle_memory

Regarding guitar learning, practicing & playing muscle memory simply means the process of repeating a physical motion(s) until they gradually become automated, or second nature, & then you can do them without having to think or focus all the way through them. You can just think "D chord" (for example) & your brain & hands will take care of the rest. :)

This process holds for everything from fretting & picking your first note, all the way through playing simple melodies, learning chords, chord progressions, song sections & even whole songs!

Most of this simply comes down to putting in enough practice time to get the physical motions of guitar playing in your brain & hands; in your "muscle memory". There is no substitute for hours logged on the instrument! :)

Having said that, it's possible to practice smarter or more efficiently & speed up any given learning task by isolating the specific problem.

Here's one example. Pick two chords; for example C major and A minor.

1. Get your fingers in place for the C chord, strum it once to make sure it sounds properly.

2. Mute the strings with your strumming hand to stop the sound.

3. Change your fingers to play the A minor chord, strum it once to make sure it sounds properly.

4. Mute the strings with your strumming hand to stop the sound.

5. Repeat!

The idea here is to solely focus on the motions of forming those chords & getting them to sound right every time. Don't worry about playing in time, playing a song, or anything else during this exercise. Just those two chords. When you are comfortable with those chords, pick two others to drill!

This is an exercise that works well for all skill levels. I still do this occasionally when I'm working on tricky jazz chords. Or especially if there are a lot of chords to memorize in a song. Rather than play through the song & get frustrated with any problem area, I'll just play each chord once. This helps to drill my finger placement & to reinforce my memory of the order of the chords.

The good news is that this learning process is exactly what GT's Guitar Fundamentals 1 & 2 are focused on. This is exactly the approach of the GT Courses & all the tutorials!

Hope this helps. Ask more if necessary. Have fun & best of success with your guitar learning & playing!
