Guitar fretboard

We know that sound results from the vibrations of air molecules moving through the air to our eardrums, that the speed of those vibrations is referred to as frequency, measured in Hertz, and that pitch is the relative highness or lowness of a sound. But what is music?

Learning the names of the modes (why are they sometimes called the church modes?). So weird. Making a smart flashcard deck. DPLMAL is a mnemonic.

Again, weird that I haven’t learned this by now. So, here we go. First I want to learn the Pentatonic Scales all over the neck.
