A Corpus-Based Study on Ragtime Syncopation

This paper presents a corpus-based study on syncopation patterns in ragtime. We discuss open questions on the ragtime genre and the potential of computational tools in addressing these questions, contributing to the fields of Musicology and Music Information Retrieval (MIR), and giving back to the ragtime enthusiasts community. We introduce the RAG-collection of around 11000 ragtime MIDI files ...

Jumping and Non-Jumping Genes

The term ‘horizontal transfer (HT)’ refers to the transfer of genetic material between two reproductively isolated organisms. HT is thought to occur rarely in eukaryotes compared to vertical inheritance, the transmission of DNA from parent to offspring. In a recent study we have provided evidence that a family of DNA transposons, called SPACE INVADERS or SPIN, independently invaded horizontally...

Corpus-Based Rhythmic Pattern Analysis of Ragtime Syncopation

This paper presents a corpus-based study on rhythmic patterns in the RAG-collection of approximately 11.000 symbolically encoded ragtime pieces. While characteristic musical features that define ragtime as a genre have been debated since its inception, musicologists argue that specific syncopation patterns are most typical for this genre. Therefore, we investigate the use of syncopation pattern...

Jumping Sequences

An integer sequence a(n) is called a jump sequence if a(1) = 1 and 1 ≤ a(n) < n for n ≥ 2. Such a sequence has the property that ak(n) = a(a(· · · (a(n)) · · · )) goes to 1 in finitely many steps. We call the pattern (n, a(n), a2(n), . . . , al(n) = 1) a jumping pattern from n down to 1. In this paper we look at jumping sequences that are weight minimizing with respect to various weight functio...
