Music games Rock Band and Guitar Hero are simple enough in terms of gameplay, but testifying to the power of people’s passion for music, their impact has been staggering. At a time when purchasing recorded music has waned from a 90s peak, downloads for games are proving surprising growth, despite pundits predicting the segment would cool off. The talents of the Harmonix team attracted the collaboration of the download-averse surviving Beatles and family members. But most importantly, the popularity of these games has translated into renewed interest in learning to play real instruments. It’s no accident popular music chart sales are surging, or that you will now find a new selection of digital and acoustic (but serious) instruments at your local Best Buy, often located right next to the games section. (Even as a witness to this trend, I was surprised recently to pick up an extra KORG nanoKONTROL in the aisle next to Rock Band.) Heck, even sales of music notation software are growing.

I’m uncertain of the extent to which a game like Rock Band can be identified as the cause of these trends, but there’s no question that popular music making is on the rise, and games are part of the shift. Perhaps it’s a matter of games changing the way people feel about making music. After all, a lot of early music training is very much like a game: to learn a new instrument, you simplify the playing of that instrument into more basic exercises. Obviously, that helps develop chops, but it also boosts confidence, giving a music student a feel for what it’s like to play successfully. (And, let’s face it, even experienced pro players sometimes need to defeat anxiety.)

The dark side of all of this has been that the music itself has been limited to a narrow selection of top-of-the-charts hits and popular classic tracks. Rock Band Network doesn’t yet address the limited instrumentation (guitar, bass, drums, voice), but it does open production to a new range of artists – and that, in turn, could be the beginning of much more to come. By allowing anyone to author and distribute tracks for a nominal subscription fee on Microsoft’s Xbox creation community, Rock Band Network is all about opening floodgates.

Having followed the story here on CDM since last year, I’m thrilled that the Rock Band Network store itself is now live. The results run the gamut from relatively big-name artists to more obscure contributions. (Phone giant T-Mobile will pony up some cash to highlight an “Artist of the Month” from the community, in the interest of shining a spotlight on lesser-known acts.) The only bad news is, while the store is international, the Rock Band Network isn’t immune from the music industry’s trouble crossing national borders; as our own Jaymis discovered to his dismay, countries like Australia are left out. I hope to talk to Harmonix and Microsoft about how they plan to make these kinds of efforts more global with time.

The independent game Osmos won our hearts in 2009, with transcendent, meditative gameplay built on simulated particle physics, starting as a floating wonderland and ending with some deliciously punishing difficulty. But it’s the soundtrack that sealed the deal: ambient-tinged work by artists like Gas 0095, Julien Neto, Loscil, and High Skies helped us imagine an unseen, microscopic (or perhaps macroscopic) world. Their sonic craft is a great example of what digital music can be.

Now, I’m pleased to offer a lot of that music for your listening pleasure, for free. It’s one of the rare game soundtracks you’d want to hear even after having heard it on repeat while solving some of the title’s trickier puzzles. A huge thanks to the artists, whose generosity made this compilation possible – check out their work if you haven’t already.

The release is overdue, but it comes at a good time. By the end of last year, Osmos migrated from its initial, Windows-only release to Mac, too. Owners of multitouch PCs have been treated to a multitouch version on Games for Windows Live. (I’m still working on loaning a multitouch laptop; stay tuned.)

The most recent news, as seen on Synthtopia and the Microscopics blog: an iPhone version of Osmos is coming soon.

If you’ve already gotten the game but got stuck on Epicycles (ahem), we have a solution for that, too – see the recently-released video from the game developers, who must have heard your pain. (Man, in my day…)

We have two formats for listening:

One Big Game is a charity assembled by game developers to raise money for children’s organizations. Musical games look to figure prominently in the series. Design legend Masaya Matsuura (PaRappa the Rapper, Vib-Ribbon), father of rhythm games and without whom there likely would be no Rock Band or Guitar Hero, has signed. And the first title out, from Zoë Mode, is musical in nature, too, in a game called “Chime.”

Chime is an elegantly-designed game and a lovely way to unwind, particularly with Philip Glass’ gorgeous “Brazil” in the track list. (“Brazil” has Glass’ usual musical furniture, but the cut, taken from the Aguas da Amazonia album, is executed by the extraordinary Uakti ensemble and takes on a new set of timbres.) One relevance to Create Digital Music – it’s not a bad way to take a break after a production and/or programming stint. The game is 500 Microsoft Points for Xbox Live, the lion’s share of which goes to children’s charities.

Fun as it is, Chime also reveals some of the limitations of musical gameplay; whether or not that’s a fault is really up to the user/gamer. The gameplay is almost a direct homage to Lumines, Tetsuya Mizuguchi’s puzzle game. As with Lumines, you place interlocking blocks into patterns, with the basic mechanics derived from Tetris. Chime is actually slightly simpler; there’s no color matching involved, only the creation of matching “quads” – areas of the grid 3×3. The more of the space you manage to fill up, the higher your score, which is oddly satisfying. (Sure, other animals have survival instincts and stuff like that imprinted in our brain; humans seem to be basically obsessive-compulsive as a species. Great.)

How is this a “music game” and not just a variant of Tetris? Well, again borrowing (liberally) from Lumines, Chime has a playback “wiper” that scrolls across the screen from left to right. In fact, it’s not so much that Chimes or Lumines are music games as it is that digital musical interfaces in general tend to use left-to-right, linear, step-sequencing grids. The tracks are all pre-composed, whether Glass or Moby, so the blocks themselves just add little musical “flairs,” kept in time to the music.

The one thing you probably aren’t thinking while watching the Grammys is “wow, look at this amazing showcase for independent music.” (Last night, I expect you were thinking something more along the lines of, “I was supposed to get 3D glasses for this? Augh! I’m dizzy! Switch it off!”)

But keep score, and independent artists and labels are a huge part of the Grammy Award-winning roster. And with indies invading even the most mainstream of music events, that’s a strong indication of how big a part of the industry independent music is becoming. (Side note: yes, I’m aware that the definition of “indie” is murky at best. But looking at the broad trend, there’s still something here. There’s a difference between an artist self-releasing and being on RCA; examples below. In short, this may not be what most of us would call “indie,” but it’s a big shift away from the traditional role of the “major.”)

Want an example? How about “Album of the Year” Taylor Swift’s Fearless? And it’s not incidental that Taylor Swift thanked said label for allowing her to write all her own songs. (My own personal fandom of Taylor Swift ranks up there somewhere with Kanye West’s, but I think that’s worth noting.)

One of the groups keeping score at the Grammy Awards is A2IM, a not-for-profit that represents the independent music community. This year, says A2IM, some 43 awards can be considered “indie,” including the categories Pop, Rock, Alternative, Country, New Age, Jazz, Gospel, Tropical Latin, Tejano, Norteno, Bando, Americana, Bluegrass, Blues, Folk, Hawaiian, Native American, Zydeco/Cajun, World, Spoken Word, Comedy, Surround Sound, & Classical genres, and also scored for Best Recording Package.

Games really are reshaping music. Despite their relatively simple gameplay, the Guitar Hero and Rock Band franchises originated by developer Harmonix are stimulating interest in real music making. It’s no accident that you can walk into a Best Buy and, next to aisles of video games, find a growing selection of serious musical instruments and technology.

These titles are also stimulating interest in music and artists and producing a new distribution outlet, at a time when the distribution picture for music can seem bleak. But until now, that outlet has been limited to big acts, big tracks, and big deals with big labels. It has only promoted music you already know, not the discovery of new music. Rock Band Network could change all that.

We took a detailed look in August at how Rock Band Network worked technically, and how authoring a song for RBN could give you the same level of gameplay and choreographed graphics that the official Rock Band tracks get. But now here’s the big news: at long last, RBN is opening to the general public, starting with an open beta for artists and play-testers.

What it is: Rock Band Network is a new set of authoring tools (built around Reaper), a submission process (built around Microsoft’s Xbox 360 XNA Ceators Club), and an upcoming store to host indie tracks called the Rock Band Network Music Store.

What it costs: Rock Band Network membership is free, but you’ll need a $99/year XNA Creators’ Club Premium account to submit or test music.
