Canary song is hierarchically structured: Short stereotyped syllables are repeated to form phrases, which in turn are arranged to form songs. This structure occurs even in the songs of young isolates, which suggests that innate rules govern canary song development. However, juveniles that had never heard normal song imitated abnormal synthetic songs with great accuracy, even when the tutor song...

This report analyses data collected from Last.fm and used to create a real-time recommendation system. We collected over 2M songs and 1M tags and 372K user's listening habits. We characterize users' profiles: age, playcount, friends, gender and country. We characterized song, artist and tag popularity, genres of songs. Additionally we evaluated the co-occurrence of songs in users' histories, wh...

In the 18th century Istanbul, different congregational and ethnic groups started to come together in public sphere. This created an environment of cultural transfer exchange among various congregations, that reached its climax at beginning 19th century. Turkish classical music be written Hamparsum notation which adapted ancient note system Armenian church music. The elements Rum Church Profan M...

It is well established that the lunar cycle can affect the behaviour of nocturnal animals, but its potential to have a similar influence on diurnal species has received less research attention. Here, we demonstrate that the dawn song of a cooperative songbird, the white-browed sparrow weaver (Plocepasser mahali), varies with moon phase. When the moon was above the horizon at dawn, males began s...

The elaborate songs of songbirds are frequent models for investigating the evolution of animal signals. However, few previous studies have attempted to reconstruct historical changes in song evolution using a phylogenetic comparative approach. In particular, no comparative studies of bird song have used a large number of vocal characters and a well-supported, independently derived phylogeny. We...

General characteristics of Singapora Dworakowska and a key to known species of the genus are provided. Six new species, Singapora candela, S. excedens, S. falcata, S. longiantrosa, S. triacantha and S. yingjiangica spp. nov. are described and illustrated, with two new records, S. shivae Dworakowska from China and S. bannaensis Song & Li from Thailand.

From the works of mathematical properties of songs, we construct the phylomemetic trees of Indonesian ethnic and traditional songs. The memeplexes are then reflected by the used notes and respective durations as they exhibit the Zipf-Mandelbrot law, the gyration coefficient, “spiraling effects”, and the dynamic entropy shown in the structure of the songs. The cladistic techniques yielding phylo...
