The news is still sketchy, but in an ambiguously-written news piece by ISNA, it appears that at least one Iranian university which teaches music to its students has been instructed not to teach any western musical instruments to their students in the new academic year. Such a decision, if true, will mean that Iran will no longer train musicians who can be members of large orchestras like this.
