1) What's a good voicing for each of these chords? Keep in mind that a voicing doesn't have to use all 6 strings. If you want, try to come up with a couple good voicings for each chord, it's good practice. If you can get your hands on a guitar, try fingering those voicings, see if they're actually comfortable.
2) One thing we didn't cover in the video is guitar tab. This is an alternate notation system guitarists use where they just mark which fret on which string you're supposed to play. they're notated highest string on top, and make it really easy for guitarists to quickly pick up new songs. for instance, the arpeggiation Milo played in the video might look like this:
E - - - - - - - - - - - - - - - -
B - - 1 - - - - - - - 0 - - - 1 -
G - - - 0 - - 2 - - - - 0 - - - 0
D - 2 - - - - - 3 - 3 - - - 2 - -
A 3 - - - - 3 - - - - - - 3 - - -
E - - - - 1 - - - 3 - - - - - - -
Now, looking at that and using what you know about guitar tuning and intervals, what are the notes Milo played? If you can, turn this into standard notation. If you want to try more, look up the tab to any song you like and try to figure out what's actually going on.
3) Try writing some stuff for (Or even better, on) guitar! There's really no better way to practice instrumentation than just doing it. If you can't play, that's totally fine. See if you can find a friend who can and ask them if they can play things for you. It really is the best practice. Even if you're just spelling voicings and seeing if they're playable, there's no substitute for real experimentation with the instrument.
So that's that! Post your answers (To the first two, at least...) below or in the comments on the video, and we'll see you next week!
