“…Algorithms such as that described by Snydal and Hearst create melodic landscapes and harmonic palettes from transcriptions of jazz improvisations [27], while Miyazaki et al use cylinders whose height, diameter and color represent pitch, volume and duration information of the notes in the score. In the latter algorithm, the visualization can be represented both at an overview level and also at a detailed level according to user preference [19]. Ciuha et al describe an approach to visualize concurrent tones, using color to highlight the harmony [4].…”

Figure 1: Augmenting piano sheet music with harmonic fingerprint glyphs facilitates the identification of recurring harmonic patterns and the comparison of musical parts to understand differences in the note distribution. Here, an excerpt from Chopin's 'Grande Valse Brillante' is augmented with the fingerprints showing a recurring pattern in the first four glyphs. ABSTRACTCommon Music Notation (CMN) is the well-established foundation for the written communication of musical information, such as rhythm or harmony. CMN suffers from the complexity of its visual encoding and the need for extensive training to acquire proficiency and legibility. While alternative notations using additional visual variables (e.g., color to improve pitch identification) have been proposed, the community does not readily accept notation systems that vary widely from the CMN. Therefore, to support student musicians in understanding harmonic relationships, instead of replacing the CMN, we present a visualization technique that augments digital sheet music with a harmonic fingerprint glyph. Our design exploits the circle of fifths, a fundamental concept in music theory, as visual metaphor. By attaching such glyphs to each bar of a composition we provide additional information about the salient harmonic features available in a musical piece. We conducted a user study to analyze the performance of experts and non-experts in an identification and comparison task of recurring patterns. The evaluation shows that the harmonic fingerprint supports these tasks without the need for close-reading, as when compared to a not-annotated music sheet.

“…A plethora of real-time music visualizers provide stimulating experiences by reacting to the music's tempo, rhythm, strength, or pitch. Diverse varieties of geometric designs have been utilized in the visualization of musical rhythms, such as bars [22,38], radial forms [24], spirals [9], isochords [4], arc diagrams [56], and three-dimensional structures [39,55]. One of the earliest works by Kubelka [31] proposes a proof-of-concept interactive music visualizer comprising three primary units -a sound analyzer, a visualization module, and a scene editor.…”

“…Moreover, the mathematical models of time and frequency signals [20] are also among the factors employed for musical analysis and synthesis. A variety of works [10,23,38,39] have also interfaced with MIDI or Musical Instrument Digital Interface that display visual illustrations so as to better comprehend and conceive the tonal patterns of the audio. A program to parse MIDI data and automatically generate three-dimensional graphical depictions was developed by Smith and Willams [47].…”

“…Smith and Williams 10 discussed the possibility of visualizing MIDI in 3D space using color to mark timbre. The comp-i system 11 shows the structure of music as a whole using 3D piano roll visualization. Its main goal is to allow users to perform visual exploration of a given MIDI dataset in an immersive and intuitive manner.…”

Experienced musicians have the ability to understand the structural elements of music compositions. Such an ability is built over time through the study of music theory, the understanding of rules that guide the composition of music, and countless hours of practice. The learning process is hard, especially for classical music, where the rigidity of the music structures and styles requires great effort to understand, assimilate, and then master the learned notions. In particular, we focused our attention on a specific type of music compositions, namely, music in chorale style (four-voice music). Composing such type of music is often perceived as a difficult task because of the rules the composer has to adhere to. In this article, we propose a visualization technique that can help people lacking a strong knowledge of music theory. The technique exploits graphic elements to draw the attention on the possible errors in the composition. We then developed an interactive system, named VisualMelody, that employs the proposed visualization technique to facilitate the understanding of the structure of music compositions. The aim is to allow people to make four-voice music composition in a quick and effective way, that is, avoiding errors, as dictated by classical music theory rules. We have involved 40 people in testing VisualMelody in order to analyze its effectiveness, its usability, and the overall user satisfaction. We partitioned the people involved in the evaluation study into two groups evenly splitting the musical expertise. Then, we had one group use VisualMelody without the visualization facilities and the other using the tool enhanced with our visualization. On average, people in the group that used our visualization were 60% faster and produced music with less errors.
