What’s the biggest obstacle in music making? For most people, it’s basic musicianship. I’m not at the Macworld keynote, but the well-done TUAW liveblog tells me that Apple has in fact offered a product hoping to solve that. GarageBand ‘09 will come with built-in musical training, with add-on “celebrity” training packs for US$4.99 each. It’s great news, but it also makes me hopeful that the music education end of music technology will develop and flourish more than it has – along with music education in general.

As far as Apple’s new offerin, if I’m understanding this correctly, you’ll first need GarageBand ‘09 via iLife ‘09: that’s US$79 to upgrade, US$99 new, or free on a new Mac. You’ll then get nine lessons on the basics. (It’s actually not clear that there’s much else improved in this release of GarageBand; given Apple’s focus on incremental, specific feature improvements, this may be it.)

To get additional tutorials, you pay $4.99 a lesson. The pay-off is lovely, though: on-screen frets and keys show you what to do if you’re an absolute beginner, and the likes of John Fogerty, Colbie Callat, Sting, and Sarah McLachlan are the teachers.

There’s no question about it: this is a great way to get casual musicians hooked on music and music learning, and even if you’re not a Sarah McLachlan fan, that’s good news for all of us. But it’s also just the beginning.

Mac users are already assuming this will sell a lot of Macs, but that was the assumption with GarageBand. Not to burst the bubble here, but I think you’d probably be a little silly to invest in an entire Mac for a few minutes of video training; I’m not even sure if it’s worth $100 if you don’t have much other use for iLife. But it is a significant offering, and I think the smartest idea here is offering $5 lessons. It’s so smart, in fact, that it’s too bad that GarageBand is apparently a prerequisite. So you ought to be smelling an opportunity if you’re in the training business: inexpensive, on-demand training could be addictive, even if traditionally this sort of lesson has been sold in a bundled or subscription form.

Apple is doing informal, video-based learning in a new way. It should be great for casual users. But for real music lovers wanting to go deeper, there are already other products, and this should be an impetus for them to both step up the quality of their delivery and capture GarageBand graduates in a new way.

Three tools immediately spring to mind.
