Percepciones del profesorado de música sobre un nuevo software para la evaluación de la entonación en instrumentos musicales

Résumé

Intonation is an essential skill in learning musical instruments, especially those with variable intonation, such as brass and bowed stringed instruments. A frequent problem is that beginners encounter many intonation difficulties on these instruments during their learning. Therefore, they spend a great deal of time practicing them, as do teachers in correcting the related errors. This validation study is part of a larger study that has designed and implemented software Plectrus to evaluate in real time the intonation in the learning of brass and bowed stringed instruments. To find out whether this software responded to the educational needs detected, a statistical validation study was carried out based on a questionnaire that was completed by teachers from music schools and conservatories in Spain and Chile (n=41). The questionnaire included three validation dimensions (technical, educational, and global). Also, a dimension on educational digital technology use, and professional experience, gender, age, and pre-service formation acted as covariates. The quantitative results obtained were triangulated with those from qualitative data collected in two focus groups (n=10) to lend credibility to the interpretation of the results. The finding of this study indicates that Plectrus has been evaluated very positively by teachers in all three validation dimensions; correlations were found between the three dimensions, as well as a positive correlation between the use of digital educational technology and the evaluation of the software. The results of this validation by teachers support the effectiveness and usefulness of the software for the development of intonation in brass and bowed stringed instruments at the initial level of musical studies.
