Symphony No. 7

Sinfonie Nr. 7, Deep Sea (2008 - 2011)

This symphony is dedicated to our distant relatives living in the deep sea. All known living organisms are built using the information stored in the DNA. The DNA consists of two long polymers of simple four unites called nucleotides. For more information see here.

I. Allegretto, Dumbo-squid [1] is living in the deep sea down 300 to 5000 m. It is not well known what he is doing there. What looks for a human being as a black sinister world might be for the Dumbo like living in a kind of a ghost train. He is able to ignite his own light as it is the case for 90 % of the deep sea creatures. But as a living animal he needs food, a mate, has to escape predators. If I listen to my music I never need any picture but writing music, a picture (in this case Dumbo) may well give some hints or ideas. The first four measures as well as the instrumentation of the symphony is shown here: Sin7101.GIF (page no. 1). My program ScoreEd4 I use to edit the hand written notes does not play the music. I have to do it myself. 

II. Lento, Bolinopsis sp. [2], 20 cm. Bolino, as I call him,  is a completely transparent jellyfish living down there somewhere. This new found creature is not as peaceful as it looks like. He ingests small copepods (Ruderfusskrebse), small shrimps and even other jellyfish. He may also have these terrible sting weapons. Some species of jellyfish are even very dangerous for humans. They cannot swim very fast. But nevertheless are very successful. For more information about jellyfish see here. The first page of this movement is shown here: Sin7201.GIF.

III. Allegro vivace, Histioteuthis sp. [3], 25 cm. I describe here as before only the "actor", Histioteuthis sp., and not the music itself. Histio as I call him is living in a depth between 400 and 1200 m. He possesses sophisticated bioluminescent light organs. The duration and intensity of the light-emitting photophores are regulated with filters, reflectors and "eyelids" corresponding to the depth and the light from the environment. They even can be shut down entirely. That is really amazing. The first page of this movement is shown here: Sin7301.GIF.

IV. Lento, Enypniastes eximia [4], 35 cm. This deep water sea cucumber, I call him Enypnia, lives between 500 to 5000 m below sea level and belongs to a small group of free swimming sea cucumbers. It swims slowly and gracefully sometimes way above the sea bottom. Since the animal is transparent one is able to recognize its inner organs from the outside. I don't know if the light comes from the animal itself or rather from the flashlight of the photographer. It looks pretty strange and one doesn't belief that it belongs to the echinoderms like the sea urchins. The first page of this movement is shown here: Sin7401.GIF.

V. Allegro vivace, Paraeuchaeta barbata [5], 12 mm. This copepod (german: Ruderfusskrebs) lives between 200 and 1500 m below sea level. Copepods typically 1 to 2 mm long are usually the dominant members of zooplankton in the ocean and in fresh water. The large pair of antennae are the main source of propulsion, beating like oars to pull the animal through the water. Paraeuchaeta barbata is a predator and my feed on their smaller relatives. See also the interesting article Copepod in Wikipedia. First page here: Sin7501.GIF.

VI. Allegro vivace, Mesonychoteuthis homitoni [6], 9 m !! This huge squid lives up to 2200 m below sea level. The arms and tentacles staffed with hundreds of rotating hooks makes him a dangerous predator. A real monster! He has been chosen as the last actor in this deep sea world. First page here: Sin7601.GIF.
