2013Previous research in expressive music performance has described how solo musicians intuitively shape each note in relation to local/global score contexts. However, expression in ensemble performances, where each individual voice is played simultaneously with other voices, has been little explored. We present an exploratory study in which the performance of a string quartet is recorded and analysed by a computer. We use contact microphones to acquire four audio signals from which a set of audio descriptors is extracted individually for each musician. Moreover, we use motion capture to extract bowing descriptors (bow velocity/force) from each of the four performers. The gathered multimodal data is used to align the performance to the score. Then, from the aligned data streams, we obtain a note-by-note description of the performance by extracting note performance parameters. We apply machine-learning algorithms to induce human-readable rules emerging from the data. The dataset consists of three performances of Beethoven’s quartet n° 4 in C minor by a group of professional musicians: a “normal”, a “mechanical” and an “over-emphasized” execution. We run our analysis on the three conditions separately as well as jointly, deriving rules specific to each condition and rules of general domain. Apart from encoding knowledge of expressive performance, the results shed light on how musicians' roles in ensemble performance.

Aural-Based Detection and Assessment of Real Versus Artificially Synchronized String Quartet Performance
Papiotis, Panos; Herrera, Perfecto; Marchini, Marco (University of Jyväskylä, Department of Music, 2013)In a musical ensemble musicians can influence each other’s performance in terms not only of timing but also in other aspects of the performance such as dynamics, intonation, and timbre. The goal of this work is to test ... -
Coadsorption of NRR and HER Intermediates Determines the Performance of Ru-N4 toward Electrocatalytic N2 Reduction
Wu, Tongwei; Melander, Marko M.; Honkala, Karoliina (American Chemical Society (ACS), 2022)Electrochemical N2 reduction (NRR) to ammonia is seriously limited by the competing hydrogen evolution reaction (HER), but atomic-scale factors controlling HER/NRR competition are unknown. Herein we unveil the mechanism, ...
