A través del contrabajo: consejos para el maestro y el estudiante.
The objective of this research is to make available to Mexican double bass players diverse experiences shared by students and teachers (national and foreign) regarding the teaching and learning of double bass. On the other hand, to complement the contributions made by students and teachers of this instrument a historical analysis is presented regarding the evolution of music education from the twentieth century. In addition, some reflections on instrumental teaching according to the experience of scholars of musical pedagogy such as Emile Jaques-Dalcroze, Cecilia Jorquera Jaramino, Violeta Hemsy de Gainza, Paulina Derbez, Valentin Solis Aguilar and Bejamin Whitcomb in order to find the links between theory and practice in order to explain useful considerations in the teaching-learning process of the contrabass. For the realization of the present project the qualitative research model was used as a tool for data collection, on the one hand, the interview and the electronic questionnaire are used, futhermore, the compilation of documents that have studied the topic, the teaching of the instrument in general and the specific contrabass. The interviews were conducted in two groups, the first was composed by the double bass teachers: Donovan Strokes (USA), Barry Green (USA), Claus Freudenstein (Germany), Thierry Barbe (France), Alonso Hernández Prado (Mexico, Queretaro), Enrique Aguilar Canuto (Mexico, Querétaro), Claudia Gabriela Arroyave Mendoza (Mexico, Nuevo Leon) and Jose Ricardo Garcia Fernandez (Mexico, Queretaro). The second group was composed by 23 double bass students from Chiapas, Coahuila, Mexico, Jalisco, San Luis Potosí, Querétaro, Morelos, Baja California and Zacatecas. Finally, for the analysis of the discourse of the questionnaires and the interviews the model suggested by Bertely (2000) was used, in which he proposes the systematization and analysis of the social categories, the categories that the interpreter identifies and the theoretical categories. In the results the main problems are found faced by teachers and students of the instruments and at the same time that reflections and advice are exposed to deal with the problems exposed.
