    Summary:This paper describes the development and evaluation of the UIs and scores of musical performance system. The aim of this research is to provide a musical tool for elderly people and caregivers. Another aim of this research is to use the performance system and score database to conserve some non-Western music genres. The UIs are designed on a tablet PC, which look like keyboards. Four UIs with scores are evaluated by young people and elderly people: plain keyboard with staff notation score, and keyboards of note name/number/color representation with scores of the same representation. The results of the experiment indicate that the number representation would be useful to most people and the note name/color representations would be useful to some people. This system also have a UI of koto music which is one genre of Japanese traditional music. This system can be used for the explanation of the difference between the temperament and scale of koto music and those of Western music. Scores for musical performance system and scores of koto music are also discussed. This research provides a system to add melody and rhythm using score DB to the lyric input by a user. This system can also explain the melisma of koto songs and asynchronicity of the rhythms of voice part and koto part.
  • A Study on the UI of Musical Performance System and Score Representation, DEGUCHI Sachiko, AAAI 2018 Spring Symposium Series Technical Report, AAAI 2018 Spring Symposium Series Technical Report, 207 - 211, Mar. 2018
    Summary:This paper describes the development and evaluation of the UIs and Scores of musical performance system. The aim of this research is to provide a musical tool for elderly people and caregivers. The UIs are designed on tablet PCs, which look like keyboards. Five UIs are evaluated: plain keyboard, and keyboards with note names, numbers, colors and shapes. A staff notation score was used for the plain keyboard, and four types of scores represented by note names, numbers, colors and shapes were used for other UIs. The result of the experiment indicates that the UIs and scores of note name representation and number representation would be useful to play for people who are not familiar with staff notation and that those of number representation would be useful to play and sing at the same time. The result also indicates that the UI and scores of color representation could be used for some people who have difficulty reading numbers. It is also indicated that people in their 60s and 70s can use the UI and scores of number representation.

    Summary:This paper describes the experiments of human factors on pen input of LCD tablet. In the first experiment, one of three conditions (the display time of input area, the size of input area, and the distance between current input area and next one) is changed and correct inputs are counted in each session. The next experiment is designed to measure human memory on rhythmic patterns (sequence of quarter notes and eighth notes). This paper also describes a prototype of improvisation system, where users can select melodic patterns and pitches on LCD tablet. The rhythmic patterns used in the previous experiment are applied to the improvisation system.
  • A Prototype System for Melody Synthesis using Existing Music,   2006 06
    Summary:This paper describes the prototype system that extracts phrases from existing music and that synthesizes new music using those phrases. This prototype system builds phrase database for each composer and synthesizes the music by choosing the phrases alternately from two databases. The system makes the feature vector for each phrase, and then chooses the nearest one to generate the next phrase. To make the feature vector, the system calculates the average of pitches in a phrase, the average of durations in a phrase, the difference between max pitch and min pitch in a phrase, etc. The melodies generated by this synthesis method are more natural than a random sequence of phrases, however, it is difficult to evaluate the effects of the feature vector. This system can synthesize the melodies by reusing huge music resources.

  • Development, Utilization and Evaluation of the Learning System for Counter Circuits, IEICE Technical Report, 113, 67, 11, 16,   2013 05
    Summary:This paper describes the learning system for counter circuits to support experiments. This system explains a state transition by synchronizing a circuit diagram, an explanation text, a timing chart, and a state transition table. This system also uses audio recordings for the explanations. This system provides exercises about the contents. This system was introduced to the experiment for the freshmen of the faculty of engineering. The results of the experiment, the answers of questionnaires, correlations between the result and the answer, and correlations between two answers are analyzed to evaluate this system. The answers of questionnaires are also compared to the answers of questionnaires of the learning system for flip-flop circuits.
  • Research on the musical interface using melodic patterns and the acquisition of melodic patterns, 46, 69, 74,   2012 12
    Summary:This paper describes the analysis of melodic patterns and the improvisation system using 4-note melodic patterns. This improvisation system has a graphical user interface which is composed of pattern area and note area. A user selects a pattern in the pattern area and inputs 4 times in the note area, and then 4-note melodic pattern is generated. This system also has an assistant mode for the rhythm and an automatic playing mode. This system provides a learning function for melodic patterns and a learning function for rhythmic patterns. Both learning functions are based on Genetic Algorithm. Several learning parameters can be set by the users of this system. By using these learning functions, melodic patterns and rhythmic patterns are acquired based on the preference of users.
  • Study on Counter Circuits in the Learning System of Sequential Circuits, 46, 75, 80,   2012 12
    Summary:This paper describes the learning system of counter circuits which was developed as an addition to the learning system of sequential circuits for beginners. This system explains each state of counter circuits by synchronizing a circuit diagram, an explanation text, a timing chart, and a state transition table. This system also uses audio recordings for the explanations. This system provides exercises to test the student's comprehension. Nine students used this system to evaluate the system. This system will be introduced to the experiment for the freshmen of the faculty of engineering.

    Summary:This paper describes the knowledge representation of the melody and rhythm in koto songs based on the structure of the domain: the scale, melisma (the melody in a syllable), and bar. We have encoded koto scores and extracted 2,3,4-note melodic patterns sequentially from the voice part of koto scores. The 2,3,4-note patterns used in the melisma are limited and the percentages of top patterns are high. The 3,4-note melodic patterns are examined at each scale degree. These patterns are more restricted than the patterns that are possible under the constraint of the scale. These typical patterns on the scale represent the knowledge of koto players. We have analyzed rhythms in two different ways. We have extracted rhythms depending on each melodic pattern, while we have extracted rhythms depending on each bar. The former are complicated and the latter are typical. This result indicates that koto players recognize melodic patterns and rhythmic patterns independently. Our analyses show the melodic patterns and rhythmic patterns that are acquired by koto players. These patterns will be applied to the description of variations of the melisma to build a score database. These patterns will also be applied to a composition and education. The melodic patterns can be extracted from other genres of Japanese traditional music, foreign old folk songs or chants by using this method.
