The Aeolian Harp is named for Aeolus, the ancient Greek god of the wind. Wind harps are the oldest forms of automatic music. The app uses the wind harp as a metaphor and allows the user to create relaxing animations and sounds without musical knowledge.

Touches and strokes generate visualizations and sounds which evolve in time.

User defined parameter and color schemes can be used to explore the manifoldness of the underlying particle system.

The compass can be used to locate the following instruments in the four directions of the winds: Balalaika, Celtic Harp, Guitar, Gamelan, Guzheng, Kalimba, Koto, Marimba, Orchestral Harp, and Sitar. Each of these instruments can be assigned to a compass direction with a double tap on a cardinal point.

The acceleration sensor is used to simulate the impact of gravity on the flowing particles. (You must increase the impact of gravity in the parameter settings to see the effects.) Other parameters can be used to control the duration of the sounds. Endless loops, for instance, can be created by a reduction of the evaporation parameter and an increase of the elasticity of the particles.

Snapshots of the animation can be sent via e-mail.

Recommended for headphones and external speakers (especially the speakers of the iPod and iPhone may distort high and low sounds).

Love this

Great for autistic and 2e kids

Love your app! I have bought 600+ apps (conservatively), and I use this one the most when I want to relax. I have an entire wall of the art that has been created from the app, and have had people ask about how I was able to come up with such gorgeous digital art, when they know I have no visual art ability. ;-) I always take their iPads away from them and find the harp, and tell them "mystery solved!"

I also use the app to teach rudimentary music theory to my autistic and 2e (twice exceptional) students. They tend to love everything about the app, and even if they dont use it to learn much at the time, it helps calm them if they become agitated during a lesson.

While I am a rotten visual artist, i am a pretty decent musician and recording artist with multiple releases (most of them are even in the iTunes store, and I have a couple of Grammy nominations under my belt as an indie artist) ,and I run my own label for other artists as well. Though I can use multiple means of recording the harp into a DAW, it would be SO great if this app had a recording function! Maybe I am just missing it, but I have scoured the manual and worked on the app so much, I feel as though I would have run into it by now.

Thanks for the great app, and for allowing for feedback.
