An Exploratory Study on the Acoustic Musical Properties to Decrease Self-Perceived Anxiety

Musical listening is broadly used as an inexpensive and safe method to reduce self-perceived anxiety. This strategy is based on the emotivist assumption claiming that emotions are not only recognised in music but induced by it. Yet, the acoustic properties of musical work capable of reducing anxiety are still under-researched. To fill this gap, we explore whether the acoustic parameters relevant in music emotion recognition are also suitable to identify music with relaxing properties. As an anxiety indicator, the positive statements from the six-item Spielberger State-Trait Anxiety Inventory, a self-reported score from 3 to 12, are taken. A user-study with 50 participants assessing the relaxing potential of four musical pieces was conducted; subsequently, the acoustic parameters were evaluated. Our study shows that when using classical Western music to reduce self-perceived anxiety, tonal music should be considered. In addition, it also indicates that harmonicity is a suitable indicator of relaxing music, while the role of scoring and dynamics in reducing non-pathological listener distress should be further investigated.

MeloSol Corpus

This data report introduces the MeloSol corpus, a collection of 783 Western, tonal monophonic melodies. I first begin by describing the overall structure of the corpus, then proceed to detail its contents as they would be helpful for researchers working in the field of computational musicology or music psychology. In order to contextualize the MeloSol corpus in relation to other corpora in the literature, I present descriptive statistics of the MeloSol corpus alongside the The Densmore Collection of Native American Song and The Essen Folk Song Collection. I suggest possible future uses of this corpus including extending research investigating Western tonality, perceptual experiments needing novel ecological stimuli, or work involving the musical generation of monophonic melodies in the style of Western tonal music.

Borrowed and Original Techniques in the Trio by Leonid Hrabovsky

Relevance of the study. During several years that preceded the creation of the Trio (1964), Leonid Hrabovsky wrote many other works in various genres and forms, ranging from suites and a sonata for solo instruments, a song cycle, and a cappella choruses, to large-scale compositions for orchestra and for mixed choir with orchestra, and even two one-act operas (piano scores). The composer’s stylistic priorities had been rapidly and strikingly evolving from “social realism with a human face” as evident in the Four Ukrainian Songs, towards a much more radical “sharp” expressionism and constructivism. This evolution caused the necessary changes in the techniques utilized by the composer. Hrabovsky was deeply impressed by the article Genealogia nowej muzyki (Genealogy of the new music) of the Polish musicologist Tadeusz Zieliński that was published in the magazine Ruch muzyczny, n. 20–21, 1963. Zieliński stated that, after historical periods of monody, polyphony and functional harmony, a new sonoric and timbral era had come. These ideas inspired Hrabovsky to move towards the radical avant-garde. The object of this research is the Trio by Leonid Hrabovsky. The purpose of the study is to reveal the inherent features that differentiate the piece from other avant-garde works of the early 1960s. Methods of research include technical analysis of the musical form and its dependence upon the pitch organization of the work, as well as comparative analysis. The results and conclusions. Being composed during several days in the spring of 1964, Trio became the first piece of Hrabovsky’s written in a definitely avant-garde style. It was premiered in 1966 and since then has become one of the composer’s most frequently performed works. The reason for such a success lies in the original concept of the piece that essentially differs from the other avant-garde works of that time. When discussing Trio, Hrabovsky always stresses the influence of the Polish avant-garde music attracting him during that period. Indeed, he borrowed a lot of devices from Miniatures for violin and piano by Krzysztof Penderecki, a score Hrabovsky knew and studied at that time. However, a comparative analysis of the two works reveals serious differences between them. While Penderecki operated with purely timbral (sonoric) objects and did not pay special attention to the pitch organization, Hrabovsky composed almost a classical three movement suite with the first movement in a ternary form and the last movement in the binary form. The classical principles of the pitch organization and the distribution of the pitch structures in Trio are similar to those in tonal music. These principles have been unusually applied to the sound material that has nothing in common with tonality. A combination of the traditional and new approaches to the form provided Hrabovsky’s Trio with unique qualities which made it not only an interesting artifact of the avant-garde period but one of the most valuable and artistically perfect works in the Ukrainian chamber music.

Prediction Under Uncertainty: Dissociating Sensory from Cognitive Expectations in Highly Uncertain Musical Contexts

Predictive models in the brain rely on the continuous extraction of regularities from the environment. These models are thought to be updated by novel information, as reflected in prediction error responses such as the mismatch negativity (MMN). However, although in real life individuals often face situations in which uncertainty prevails, it remains unclear whether and how predictive models emerge in high-uncertainty contexts. Recent research suggests that uncertainty affects the magnitude of MMN responses in the context of music listening. However, musical predictions are typically studied with MMN stimulation paradigms based on Western tonal music, which are characterized by relatively high predictability. Hence, we developed an MMN paradigm to investigate how the high uncertainty of atonal music modulates predictive processes as indexed by the MMN and behavior. Using MEG in a group of 20 subjects without musical training, we demonstrate that the magnetic MMN in response to pitch, intensity, timbre, and location deviants is evoked in both tonal and atonal melodies, with no significant differences between conditions. In contrast, in a separate behavioral experiment involving 39 non-musicians, participants detected pitch deviants more accurately and rated confidence higher in the tonal than in the atonal musical context. These results indicate that contextual tonal uncertainty modulates processing stages in which conscious awareness is involved, although deviants robustly elicit low-level pre-attentive responses such as the MMN. The achievement of robust MMN responses, despite high tonal uncertainty, is relevant for future studies comparing groups of listeners' MMN responses to increasingly ecological music stimuli.

No evidence for a universal effect of major versus minor music on emotions in Papua New Guinea

Music is a vital part of most cultures and has a strong impact on emotions. In Western cultures, emotive valence (happiness and sadness) is strongly influenced by major and minor melodies and harmony (chords and their progressions). Yet, how pitch and harmony affect our emotions, and to what extent these effects are culturally mediated or universal, is hotly debated. Here, we report an experiment conducted in a remote cloud forest region of Papua New Guinea, across several communities with similar traditional music but differing levels of exposure to Western-influenced tonal music. One hundred and seventy participants were presented with pairs of major and minor cadences (chord progressions) and melodies, and chose which of them made them happier. The experiment was repeated by 60 non-musicians and 19 musicians in Sydney, Australia. Bayesian analyses show that, for cadences, there is strong evidence that major induced greater reported happiness than minor in every community except one: the community with minimal exposure to Western-like music. For melodies, there is strong evidence that those with higher mean pitch (major melodies) induced greater happiness than those with lower mean pitch (minor melodies) in only one of the three PNG communities and in both Sydney groups. The results show that the emotive valence of major and minor is strongly associated with exposure to Western-influenced music and culture, and there is no evidence for universality.

Taqsīm as a Creative Musical Process in Arabic Music

Creativity plays a major role in various musical contexts including composition, performance and education. Although numerous studies have revealed how creativity is involved in processes of listening, improvising and composing, relatively little is known about the particularities of transcultural creative processes in music. In this article, we aim to shed light on the creative musical processes underlying taqsīm performance in Arabic music. To that end, qualitative interviews have been conducted with three Berlin-based oud players from Syria. Results of a thematic content analysis show that taqsīm encompasses multiple components (e.g., a flexible form and dependency on maqam as well as tonal music) and serves various functions such as developing artistic individuality. Moreover, taqsīm is affected by interactions between tradition and novelty. We discuss the interview data within the cross-cultural experiential model of musical creativity developed by Hill (2018), offering a fresh approach to studying taqsīm which goes beyond established concepts such as the improvisation-composition continuum.

Repetition and Aesthetic Judgment in Post-tonal Music for Large Ensemble and Orchestra

Post-tonal music often poses perceptual and cognitive challenges for listeners, potentially related to the use of relatively uncommon and unfamiliar musical material and compositional processes. As a basic compositional device, repetition affects memory for music and is structured by composers in very different ways across tonal and post-tonal musical repertoires. Of particular concern is whether post-tonal music exhibits mnemonic affordances that allow listeners to experience a sense of global coherence, and whether repetition correlates strongly with aesthetic judgment. Although previous research suggests that repetition impacts aesthetic preference, empirical research has not mapped out the relationship between repetition and aesthetic judgments across a broad set of post-tonal music. Presenting 14 excerpts, grouped into three categories: tonal, modernist, and post-1970, we observed that indications of repetitions in the music for a group of 60 listeners, with and without musical training, showed significant periods of interindividual synchronization. Aesthetic judgments were assessed by means of ratings for the following parameters: familiarity with the piece, confidence of repetition responses, judgments of affordances for easy listening, coherence, similarity of moments, and recognition, as well as listeners’ liking and interest. A principal component analysis (PCA) on the joint question data and the repetition responses suggested that two factors account for 92% of variance in the data. These factors were interpreted as dominated by aesthetic judgment and repetition strength. Linear mixed-effects regression indicated that repetition strength generally differed across excerpt category, with modernist excerpts featuring lower repetition strength compared to both post-1970 and tonal excerpts. Aesthetic preference, on the other hand, was lower for excerpts in both the modernist and post-1970 categories when compared to tonal excerpts. The analysis did not reveal difference in response behavior for repetition responses as a function of musical training, though it indicated higher preference of modernist excerpts with increasing levels of musical training. Overall, the results suggest that the two factors, aesthetic judgment and repetition strength, act as independent determinants in the experience of post-tonal music.

A Cognitive Basis for Choosing a Solmization System

This article focuses on the perception and cognition involved in music listening skills as essential criteria in selecting solmization systems. Drawing on many aural key-identification studies performed by various researchers, and on the model for music perception developed by Karpinski (".fn_cite_year($karpinski_1990).") and formalized in Karpinski (".fn_cite_year($karpinski_2000)."), it concludes that the first and most fundamental process listeners carry out while attending to the pitches of tonal music is tonic inference. In addition, a tonic is inferable without reference to a complete diatonic pitch collection. Melodies that are unambiguous with regard to their tonic might never employ all seven diatonic pitch classes, they might state those pitch classes only gradually, or they might even change the collection without changing tonic. Nonetheless, listeners are able to infer tonics quickly and dynamically under any of the above conditions. According to Butler (".fn_cite_year($butler_1992).", 119), “listeners make assessments of tonal center swiftly and apparently without conscious effort” certainly well in advance of inferring or perceiving entire diatonic pitch collections. This article examines the means through which do-based minor movable-do solmization most closely models this mental process and contrasts that with la-based minor and its inherent inability to model the pitches of a musical passage until all seven of its diatonic members are explicitly stated (or at least implicitly present). This is not to say that la-based minor is ineffective, but simply that do-based minor most closely reflects and represents the way listeners infer tonality.

Using Formal Grammars as Musical Genome

In this paper, we explore a generative music method that can compose atonal and tonal music in different styles. One of the main differences between regular engineering problems and artistic expressions is that goals and constraints are usually ill-defined in the latter case; in fact the rules here could or should be transgressed more regularly. For this reason, our approach does not use a pre-existing dataset to imitate or extract rules from. Instead, it uses formal grammars as a representation method than can retain just the basic features, common to any form of music (e.g., the appearance of rhythmic patterns, the evolution of tone or dynamics during the composition, etc.). Exploring different musical spaces is the responsibility of a program interface that translates musical specifications into the fitness function of a genetic algorithm. This function guides the evolution of those basic features enabling the emergence of novel content. In this study, we then assess the outcome of a particular music specification (guitar ballad) in a controlled real-world setup. As a result, the generated music can be considered similar to human-composed music from a perceptual perspective. This endorses our approach to tackle arts algorithmically, as it is able to produce novel content that complies with human expectations.
