Step into the Light – an IYL 2015 Anthem

We are delighted to announce the release by the École Polytechnique in France of a remarkable musical tribute to the International Year of Light and Light-based Technologies 2015 (IYL 2015).

Step into the Light is an original composition urging the citizens of the world to step up and help to spread the message about the importance of light and optical technologies in their lives, for their futures, and for the development of society. The song combines a number of different styles from around the world to create a unique and original anthem for the year.

Sing it yourselves!
The song has a chorus based on a simple melody and the composers are asking interested groups around the world to get involved. One way to participate is to record yourself singing this chorus in your own language and with your choice of traditional instruments.  We will collate all contributions into a special recording for the end of the International Year and this will be your chance to have your contribution preserved for history!

You can also feel free to record a video performing the song in any language, upload it to YouTube or Vimeo and share it with us using the following ways: on Twitter using #IYL2015 or #StepIntoTheLight hashtags or send a link to the video by email to the IYL 2015 Secretariat at All videos will be disseminated through IYL 2015 social media channels.
