Here in the Instrumentarium, four gigantic instruments are used to show how sounds are produced.
To your left is the musical representative of the wind instrument also known as the aerophone: a single pipe: stand inside this orange wind instrument and wait until the sliding wall moves up and down. Does the pitch become higher or lower?
The next stop is our giant drum which represents all the so-called membranophones or unpitched percussion instruments. You're welcome to gently tap a rhythm on the drum with the palm of your hand.
Above you, xylophone plates are stuck on the ceiling. These represent all the pitched percussion instruments, also known as idiophones.
The final "gigantic instrument" of this space and sound installation is our over-sized stringed instrument which belongs to the chordophone group.
The instruments are made to vibrate by computer-controlled sound stimulators, thereby producing a unique sound experience.
In this room, there are more interactive terminals where you can discover and experience the current status of digital sound processing. Tones become visible and you can create your very own sound landscape by your own actions, for example:
A tone's sound spectrum consists of the basic tone, harmonics and noise components, and makes a significant contribution to a sound's "character". Here, you can discover an acoustic drawing studio – tones, sounds and noises are assigned individual colours and you can "paint" using your voice!
Terminal: Sound landscapes
A sonogram is the graphic representation of a sound. As on a keyboard, the low frequencies are on the left and the high on the right. The vertical direction shows the volume intensity of the sound, and the perspective plane extending forwards explains the development of a sound over time. Using these mountain and valley shapes, you can view the essential acoustic components of a sound.
Terminal: Sound morphing
By "sound morphing", we mean the transformation, or metamorphosis, of one sound into another, thereby allowing the musical parameters of sound intensity, pitch, duration and timbre to be fundamentally reshaped.
