PITCH STUDY NO.2 / THE 88 PIANO KEYS
for piano and 1 or 2 keyboards

The piece treats each key of the piano in an informative, disinformative, narrative, musical or non-musical way, starting in order from the lowest to the highest note.

The individual octaves form 7 chapters. During the composition, the listener learns, among other things, to distinguish the rustling of wind in different types of trees, how the physical condition of guinea pigs can be changed by 8-hour exposure to a 116 hertz frequency, how the 2mm insect Lesser Waterboatman achieves a sound of 96 dB with its penis, at which cytological position in the genome of the fruit fly one can adjust the pitch of its mating call, or how often the "a" occurs in all 32 Beethoven sonatas.

No animals were harmed for the piece, except for one.

Pitch Study No.2 / The 88 Piano Keys

Natural auditory environments involve many different concurrent sounds. They all sum together to one mixed signal that enters the ear. How does a human brain extract information from this permanent overwhelming chaos of surrounding sound waves? This problem is commonly known as The Cocktail Party Phenomenon.

The challenge of an auditory system in this situation is to find out which parts of the sound should be grouped together and treated as parts of the same source or object. Grouping them incorrectly can cause the listener to hear non-existent sounds built from the wrong combinations of the original components. 

The cocktail party problem is a significant challenge for computational audition and machine listening systems. The remarkable ability of a human brain to direct attention to the sound of interest while ignoring the others, as well as switching attention between the sources in a multilayered sound environment is still, to this day, unmatched by machines.

The following examples are taken from a Standard Computational Auditory Scene Recognition Test (SCASRT).  In this test, humans, on average, were able to recognize 57 different scenes with an accuracy of 78%. The best obtained recognition rate of a machine listening system was 56 % for 33 different scenes by the Cithaeron Audition Model  3.1.
