The JONC carries out its activity through meetings devoted to intensive work. Meetings imply getting all the members of the orchestra together in a certain city during a period of time that usually ranges from 7 to 15 days.

During these days the orchestra relies on the presence of a whole team of teachers who come from different orchestras and conservatories of Spain as well as of other European countries.

For the purpose of working on the selected repertoire these teachers undertake thorough work on individual as well as sectional basis.

Once the teachers end their stay, work continues with tutti rehearsals and concludes with the concerts that the JONC offers at the end of each meeting.

Apart from classes and rehearsals, meetings are complemented by other educational activities such as conferences, discussions, projections, concerts offered by the teachers, chamber music concerts, and so on.

Meetings devoted to orchestral passages as well as chamber music meetings take place once a year. Both meetings often work simultaneously.

Since orchestral passages use to be an essential part of auditions leading the entry to any orchestra, and they are usually extremely difficult for all instruments, the purpose of these meetings is to study orchestral passages minutely.

These meetings conclude with a mock audition where a board analyzes and comments on each candidate’s audition. The musicians of the JONC have thus a wider background in order to prepare future auditions in their professional career.
