Much research on the synchronization in ensemble music has been done in the past twenty years. Studies in this field frequently involve musicians performing in small groups such as string quartets. Based on some of this research and with the goal of finding new effective ways of rehearsing student ensembles, a project was carried out during sectional rehearsals of the violin section from a symphonic orchestra made up of young students. Synchronization exercises using scales and specific extracts from orchestral pieces were incorporated. 10 segments from 5 pieces were practised using various types of articulations and later evaluated concerning the following criteria: synchronization, pulse and articulation. Results showed a greater cohesion in the group and an overall better performance of the segments.
