The English Baccalaureate (EBacc) should include a wider range of subjects.
This is according to the Incorporated Society of Musicians (ISM) and Music Teacher magazine, which are calling on the government to include a creative option in the qualification.
At present, the EBacc is awarded to GCSE students who achieve A*-C grades in English, maths, science, a modern language and a humanities subject.
The ISM and Music Teacher magazine are urging education professionals to write to their MPs about the issue.
A template letter provided by the organisations reads: "Will you, as my MP, support the recent education select committee's report which called on the government to review its initial subject choice for the English Baccalaureate?
"And will you join calls for music to be included as part of a sixth 'pillar' of creative and cultural subject options, to address the omission of music and other creative subjects?"
It adds that the academic and social benefits of music education are at risk unless the subject is protected.
ISM chief executive Deborah Annetts said: "Not only is music challenging and enriching as a subject in schools, but to forget music at GCSE level is to forget the creative, social, academic, economic, emotional and intellectual benefits of an excellent music education.
"This is to say nothing of its own unique musical value."
The government has also been criticised for failing to include religion as an EBacc subject.
In an interview with the Guardian earlier this year, the Right Rev John Pritchard, Bishop of Oxford and chairman of the Church of England's Education Board, said it is "highly dangerous" to neglect the subject at this time.
He added that the Church of England is "astonished" by the government's decision not to include the subject in the qualification and suggested that there is a need for more religious education at a time when organisations such as the English Defence League are staging protests against British Muslims and tensions are running high.
