WolframTones: Wolfram does music, mathematically


With all the buzz about the new Wolfram Alpha search engine, it's easy to forget that Wolfram works on other projects, too. The developers who brought you Mathematica also put their algorithmic muscle to work to create WolframTones, a music composition engine. It turns programs from within Wolfram's "computational universe" into midi musical compositions of all different styles and pitches.

There are several variations for each musical style, ranging from hip-hop to classical. User-configurable options include picking the scale the composition will use, setting the midi instrument for each part, and adjusting the tempo. When you find a composition you like, you can download it as a midi, or have it delivered to your phone as a ringtone. I suspect Brian Eno would approve.

Tonematrix makes music-making easy and fun - Time Waster

TonematrixTonematrix by AM Laboratory is a very fun and easy-to-use music sequencing toy. It's a 16 x 16 grid of grey boxes, and clicking in a box will turn it on. Boxes that have been turned on go white, and you will quickly see that each line of boxes has its own individual tone.

You can very quickly just click and drag all over the place to get a fast sense of how Tonematrix works, but the fun is in actually arranging your notes in a way that makes sense. Luckily, it's easy to make music that sounds good because rather than using a major or chromatic scale, Tonematrix uses a pentatonic scale. You may have noticed that if you play only the black keys on a piano, it's fairly easy to play something that sounds nice - that's because together the black keys make up a pentatonic scale.

What fun is making some music if you can't save it and come back to it? The makers of Tonematrix agreed, and built in the ability to copy and paste a series of comma-separated numbers representing each individual composition. For example, if you copy the following sequence of numbers and right-click on Tonematrix and choose "Paste", you will hear my first composition with Tonematrix:

36896,32772,33280,36868,32896,32772,33280,32788,16420,32768,33286,8192,32900,32768,16966,32768

Bloom: Brian Eno's ambient music app for iPhone


Brian Eno is one of my favorite composers, so I was thrilled to hear that he was releasing a new composition tool for the iPhone. It's called Bloom, and it lets you generate, play and visualize ambient music. It's hard to explain how this works, but you basically tap the screen in different places to generate sounds. The sounds you play repeat periodically to form a composition. Because the notes are all on different cycles, the sound evolves as you let it play.

If it gets boring, you can shake the screen to clear what you have, or tap anywhere to add more sounds. If you don't feel like making anything up, there's also a "listen" mode, and once you have something you like, you can freeze it to keep new notes from being introduced. Each sound pops up as a dot on the screen, and Bloom can be mesmerizing to watch as a visualizer. I hooked my iPod up to a dock and some speakers, and let it run as a little art installation on my desk. That's pretty good for 4 bucks!

Tiny Drum Machine - Today's Time Waster

Play the Tiny Drum Machine

Created by the food folks at PixelPlanet, this half-time-waster-half-technology-demo is all fun. The Tiny Drum Machine (now in its fifth version) is a music maker where you control the notes that are played as well as the tempo of your piece. Use the simple grid to pick notes to be played and drag the bar below to set the speed. The song endlessly loops, but if you are clever you can mingle the start and end of your song so that it sounds like one long repetitive chorus. For a technology gifted but musically deficient individual such as myself getting the perfect tune has prove quite addictive.

Feeling uninspired? Hit "P" to hear a serious of random arraignments.

Graveyard Shift - zombie-busting Time Waster

With Halloween fast approaching, it's a great time to get in some practice defending your territory against zombies. In Graveyard Shift, you take aim at zombies and other creepy-crawlies, blasting them into splatters of cartoony green guts. It's a casual first-person shooter, and it's very easy to get the hang of - use the mouse to aim, click to fire. Graveyard Shift has at least 15 levels, and it might even have some secret stages I haven't unlocked yet. They key to getting good at Graveyard Shift is learning to use ...
