as a middle/high school music teacher who uses all available technologies to teach music, this could really be a good thing.
why? simple. the goal, or _a_ goal of music education is to bring a meaningful experience of music to a student. this program might help with that.
and i'm just speaking of formal music education. for someone on their own, they can use the program to get a start and then learn more/deeper as they progress.
just because it might use 'standard' chord progressions doesnt meant a person cant have a meaningful experience of music - especially an inexperienced person. again, they can always learn more later.
for those of you who negatively (and, i daresay, often uselessly) criticized up above, remember that not everyone is in the same place, musically. if only one person becomes more musical because of this then it's served its purpose, no?
