ABSTRACT=An important aspect of music performers' health and wellbeing concerns the technical control of their instruments, which has to be internalized at a subconscious level. When musicians have to perform in stressful situations (such as in front of an audience or a jury), instinct often takes over and improper technical preparation can uncontrollably increase the level of stress of the player and undermine the success of the performance. However, we believe there are unrealized opportunities for modern technologies to help music students in their technical development and assist them during their practice sessions in between visits to their teachers.

The ubiquity of PCs and mobile devices with built-in microphones, speakers and cameras has inspired the development of media technologies in support of music pedagogy. They offer an attractive potential for implementing audio signal processing algorithms addressing different technical skills of the performer, providing real-time feedback, collecting data over time and applying statistical models. Despite this potential, most available software for music instrument pedagogy remains very limited in functionality.

This study provides a survey of music edTech software available, together with the methods of use, addressed technical skills, commonalities and limitations. Results show that most current software is based on the metronome and tuner, with only a few systems that have limited abilities to follow a performance in real-time and compare it to a given score to monitor correctness of notes, intonation and rhythm. The survey also highlights a high and under-exploited potential regarding the monitoring of other more specific technical skills, which are more instrument-dependent, but no less important, such as the control of dynamic range and clarity of the attack.

This paper ends with a discussion of possible directions for future development of technologies to support the practice of music students at different levels, with some consideration for the corresponding signal processing methods that can be utilized or that need advancement.

By helping students to more efficiently achieve a high level of proficiency of their instruments with assistive technologies, we hope to minimize stress and afford better enjoyment of the music performance experience for all.
