Skifersymfonien (the slate symphony). World premiere on Sept 28th.

Since June 2024 I have been working on making instruments and music for this upcoming concert.

This is a lot of work!

First of all finding stones and slates that actually do have a good sound and resonance.

Then, how to turn them into actual instruments?

So: how to set up these instruments to fit for 6 drummers? A real Rock Band!!

And finally: how to tune the Litofones (slate marimbas) in a perfect pitch to fit with a string quartet?

Finally: composing the music for 6 drummers playing on slates and stones. Then adding some real instruments like a string quartet, vocal and violin.

Hope to see you at the concert on September the 28th - 2025.
