Design is not just what it looks like and feels like. Design is how it works...and sounds.

The web is home to thousands of sites dedicated to showcasing great design, but the majority of these are focused purely on the visual, meaning that the audible aspect of design is often overlooked.

It's an issue that user experience designer and musician, Jordan Kolasinski, addresses with his latest project, Beyond The Beep, a blog described as "a look (and listen) at the use of sounds in user experience design".

It's a project that combines his love of both design and music:

Sounds from our digital devices can achieve so much – they give feedback to our actions, communicate different states of a system, talk to us when we're not looking, and enforce the personality or brand of products. Despite their great efficiency and potential, UX sounds have a reputation of being annoying, and if their depiction in TV and film was accurate, every little thing a computer did would be accompanied by an early 1990's-sounding beep.

From a lifelong love and study of music, I'm definitely biased towards the enormous power and communicative potential of sound. I hope to use this bias to help you appreciate the tiny music our digital devices make, and to maybe even inspire the creation of more clever and communicative sounds.

So far Jordan has analysed the sounds of products such as the iPhone, Apple TV, Skype and Facebook. Speaking of which, his analysis of the latter lead to a surprising, but delightful, discovery:

When one of your friends attempts to initiate a video chat with you, a louder "ringing" arpeggio plays and repeats. What are the notes in this sound, you may wonder? It plays the first 4 notes of the F Major 7 chord, which are – I kid you not – F, A, C and E.

Pretty cool, right? Be sure to check out the rest of Jordan's post on Facebook's UI sounds here.
