Watch the Arpeggios: Level 1 online guitar lesson by Chris Buono from Guitar Gym: Triad Arpeggios
Staying on the top three strings throughout this Level, Workout #1 kicks off your first impression with a series of arpeggios in the following order: Major, augmented, minor and diminished. This collection is based off a 1st inversion vision where the lowest note is the 3rd of each chord type.
The first two sets of four bars - major and augmented - will have the arpeggios descending in major 3rds, which sounds great with moving major and augmented textures. The remaining two sets will have them descending in minor 3rds, which better compliments minor and diminished. Keep mind the my intent for you to be aware of the root of the arpeggio throughout your Workout. To do that I made each each lick starts and ends on the root of every last arpeggio you play here in Level 1!
Try not to be thrown off by the diminished arpeggios starting bar 13 with A˚/C. You'll notice they have a string skip. This is the best approach given the chord formula and voicing you have to work with.
