Rhythm complexity perception has been quite extensively studied in the last decades for its interest in the Music Information Retrieval field. However, many existing studies focus solely on the duration aspect of rhythm, and ignore the influence of other important factors. This thesis explores the impact of dynamic accents on the perception and measurement of rhythm complexity. Two listening tests were designed, respectively investigating the perception of monophonic and polyphonic patterns. In the tests participants were presented with rhythms featuring various types of accents - including patterns with constant intensity and actual dynamic drums performances - and were asked to assess their rhythm complexity. Additionally, six monophonic rhythm complexity metrics were presented and a polyphonic version of each was proposed. The quality of these metrics was analyzed using the results from the listening tests as a reference and computing the Pearson Correlation Coefficient between them. This analysis shed light on the relationship between the subjective experience of perceiving rhythm complexity and its possible quantitative description, and provides insights into the nuanced role of dynamic accents in shaping rhythm perception, in both monophonic and polyphonic contexts.
La percezione della complessità ritmica è stata oggetto di un’ampia analisi nelle ultime decadi, soprattutto per il suo interesse nel campo del Music Information Retrieval. Tuttavia, molti studi esistenti si concentrano esclusivamente sull’aspetto posizionale del ritmo, ignorando l’influenza di altri fattori importanti. Questa tesi esplora l’impatto degli accenti dinamici sulla percezione e sulla misurazione della complessità ritmica. Sono stati realizzati due listening tests, che indagano rispettivamente sulla percezione di pattern monofonici e polifonici. Ai partecipanti sono stati presentati ritmi con vari tipi di accenti - inclusi pattern con intensità costante e vere performance di batteristi - ed è stato chiesto loro di valutarne la complessità ritmica. Inoltre, sono state discusse e valutate sei metriche di complessità ritmica monofoniche, ciascuna delle quali è stata adattata anche per il caso polifonico. La bontà di queste metriche è stata determinata calcolando la correlazione tra i loro punteggi e quelli degli utenti che hanno completato i test, ed è stata così indagata la relazione tra il fenomeno soggettivo della percezione della complessità ritmica e una possibile descrizione quantitativa. I risultati offrono approfondimenti sul ruolo sfumato degli accenti dinamici nella modellazione della percezione ritmica e portano contributi significativi per la comprensione di questo tema sia in contesti monofonici che polifonici.

Abstract
Rhythm complexity perception has been quite extensively studied in the last decades for its interest in the Music Information Retrieval field. However, many existing studies focus solely on the duration aspect of rhythm, and ignore the influence of other important factors. This thesis explores the impact of dynamic accents on the perception and measurement of rhythm complexity. Two listening tests were designed, respectively investigating the perception of monophonic and polyphonic patterns. In the tests participants were presented with rhythms featuring various types of accents - including patterns with constant intensity and actual dynamic drums performances - and were asked to assess their rhythm complexity. Additionally, six monophonic rhythm complexity metrics were presented and a polyphonic version of each was proposed. The quality of these metrics was analyzed using the results from the listening tests as a reference and computing the Pearson Correlation Coefficient between them. This analysis shed light on the relationship between the subjective experience of perceiving rhythm complexity and its possible quantitative description, and provides insights into the nuanced role of dynamic accents in shaping rhythm perception, in both monophonic and polyphonic contexts.File | Dimensione | Formato | |
