This Chrome Experiment seeks to democratise music creation and allows players to create music collaboratively - this is all done in the browser - no need for software downloads - only URLs.

Upon entering the site, you choose from a selection of 19 different instruments, from acoustic and bass guitars to drum kits and keyboards. Every instrument has been carefully sampled remaining faithful to the instruments’ original sound and capturing acoustic nuances of instrument models and makes. We captured a total of 10 hours recordings edited into approximately 1,200 sound files.

You can switch instruments as often and as many times as you like. Compositions and sounds are programmed to be experienced either in ‘easy mode’ through a series of pre-created loops influenced by the mouse, or in ‘pro mode’ where the instrument is played by the user note-by-note on keyboard.

The art direction was designed to have a classical and timeless feel contrasting with the cutting edge use of technology and brought to life using HTML5 technology.

The development consists of three areas:

1. "Music workstation" a music logic engine to control music interactively including midi playback, software samplers, audio effects, routing, real-time mixing

2. “Session routing system” enabling multiple JAMs to be created simultaneously allocating users to different JAMs

3. “Synchronization component” ensuring all players in a session hear the music at exactly the same time, a prerequisite for being able to play together.

JAM sessions are created by inviting up to 3 friends by sharing a dynamically generated URL via social media networks. Members of the JAM can instant message and collectively manage global settings, eg. tempo and key in which music was being played.

To achieve the highest possible level of authenticity, accuracy and audio quality we opted to use the Web Audio API.

Given that JAM was created as a showcase of the capabilities of Chrome, it has been shared with thousands of developers in the form of in depth technical blogs, workshop sessions and conference level presentations. Our hope is that this project and these subsequent sessions will help to inspire developers to create beautiful, useful, entertaining and social experiences online using Chrome technologies.

We are exploring the possibility of recording functionality, exploring what the JAM experience might be if we introduced multi-device functionality including tablet and mobile and as well as integrating G+ hangouts. Given that this is a Chrome Experiment, the intention is to inspire developers to use the technologies in JAM with Chrome.
