Read about Karlheinz Stockhausen’s Helicopter String Quartet – one of the well-known and complex musical pieces.
What is Helicopter String Quartet?
First of all, let’s understand what is a quartet?
A quartet is a group of four people playing music or singing together.
A string quartet refers to four musicians playing music together using the stringed musical instrument.
Therefore, a Helicopter String Quartet is about musicians playing the piece independently in four different helicopters.
Facts about the Helicopter String Quartet
The musical concept
The idea of writing a Helicopter Quartet was conceived by Professor Hans Landesmann of the Salzburger Festspiele in early 1991.
The basic idea was to use the sounds of helicopter blades in conjunction with the music piece that could be recorded high up in the sky. The individual recordings from the four musicians are then mixed down to a single track for audiences to listen.
The idea of using helicopter’s for the performance came from a dream.
The first performances of the piece took place in Amsterdam on 26 June 1995
Stockhausen took around four years to come up with appropriate string section melodies.
In fact, he was initially reluctant to write the composition for Professor Landesmann’s concept.
However, after several dreams, Stockhausen submitted the melodies to Landesmann who liked it quite well.
The helicopter quartet was initially a 29-minute piece of music
However, Stockhausen revised the score to around 32 minutes by adding additional 3-minute melodies at the end of the quartet.
The score was revised only after the initial trial performances.
The last minute is mostly about the declining dynamics of the helicopter blade sounds.
Unusual system requirements
The musical performance requires exactly four helicopters, each equipped with a pilot, a musician, and a sound technician.
Other than pilots and musicians, the electronic equipment like television transmitter and three-channel sound transmitter are used to send the captured signal to the nearest auditorium.
The auditorium may have projected the visuals sent from the helicopters through proper mixing desks handled by the sound technicians.
The first performance and recording used Alouette helicopters from the Royal Dutch Air Force.
The press wasn’t impressed with the performance. However, people acknowledged the technological complexities of making such a thing work almost flawlessly are immense.
As you can see in the video, each musician is using headphone to sync with the composition. Even a milli-second lag would create a great discord in the final mix.
