We begin this issue with two papers related to musical development from the perspective of performance training. The first by Pérez-Gil et al. involves the construction and evaluation of a software solution for real-time vocal training. In this study the authors describe a pilot study involving 21 music teachers across thirteen different schools in Valencia, Spain. Using a software JMTE_9.2_Editorial_123-124.indd 123 9/7/16 2:10 PM Andrew R. Brown 124 tool (Cantus) that was able to provide assessment and feedback based upon an analysis of the users vocal audio stream that assesses the intonation of the users input. The approach uses a unique analytical algorithm to provide the performer with precise feedback, and what is presented here is an evaluation of those who participated in the study. Following on from this work is a paper by Cremata and Powell on the area of digitally mediated keyboard learning. The approach used here was to trial four different digital approaches to understand how quickly beginner students adapt to the study of an instrument, the level of retention, and the perspectives of those students involved. This was a significant study with a sample of 564 students learning a keyboard instrument and the results suggest a particular method yielded better results than three other approaches under the conditions for this case study
