In this paper we aim to expose the collaborative work we are conducting in a string orchestra. This work can be linked to the music teaching. This particular case can be linked to music schools and conservatories. Also it departs from what is stipulated in the Education Act in force throughout the entire Spanish State System.

The orchestra on which we have developed this work have many years of training, work and enthusiasm and currently consists of 16 members. This orchestra of string instruments: violins, violas, cellos and double basses is formed by amateurs and music students.

The peculiarity of this orchestra and the work on which we base this communication is that the orchestra provides an opportunity to people of all ages; children, adolescents, the elderly and retired, and even fond of music with little musical knowledge. All of them have the opportunity to experience the work of an orchestra, the concerts, the importance of teamwork so they are able to make and live music all together through string instruments.

This project started with the main objective of providing an opportunity to students, music enthusiasts adults and retirees who have minimal notions of stringed instruments to live the experience of playing in an orchestra. This provides them with the opportunity to continue developing their musical and technical qualities.

As it the musicians by playing in group develop socialization qualities such as respect for the rules of conduct, integration in a group under the command of a conductor. In addition they'd learn to assume roles such as solo players or just companion. Moreover in public performances the social sense enhances, as it exist communication with colleagues, family and the entire social environment.

Other aspects that potency the work made in an orchestra are: the development of the interpreter as it is part of a group and experience a greater responsibility. Since there is a responsibility to their fellow musician they tend to work and try harder not to look bad in front of peers and also not to harm them. Also thanks to the possibility to listen to others and be heard, the spirit of criticism and self-evaluation in the individual study of the instrument it develops to points that with the individual study we do not reach.

Also by playing in an orchestra we get to develop a sense of pitch, duration (as we start and end all at the same time), we get equal registers and a good group sound quality.

One of the Spanish Curriculum objectives is "Play Music in a Group, accustomed to hear other voices and instruments and adapt yourself to learn to balanced with the whole group." This we link it and extract it from a research that we are undertaking. This investigation pretend to obtain information on the casuistry of the curricula of stringed instruments, focusing on the violin as the Conservatories and music schools programs do not include the study of works by Spanish composers  as basic repertoire. They included it only exceptionally.

Therefore, we have proposed a series of concerts based on Spanish repertoire. So we've selected a number of works and we have raised a few sessions of rehearsals in which adults and children work together and help in assembling these. All these under our guidance and direction.
