Royal College: A Royal College in some Commonwealth countries is technically a college which has received royal patronage and permission to use the prefix "Royal".  Permission is usually granted through a Royal Charter.  The charter normally confers a constitution with perpetual succession and the right to sue or be sued independently of the members.  The charter also usually provide for rights of recourse to the Queen in Council.  Although incorporation is now cheaply and easily obtainable by registration, the distinction of a Royal Charter means that such charters are still sought by and granted to institutions considered to be in the public interest, typically learned professional societies.

GRSM: GRSM is an abbreviation for Graduate of the Royal Schools of Music (London).  This professional diploma of graduate status (equivalent to a university first degree) was open to both internal students of the Royal Academy of Music and the Royal College of Music after joint examination.  Candidates followed a three-year course including: first and second instrumental or vocal studies, harmony and counterpoint, aural training, history and analysis, conducting, composition and arrangement, and an academic thesis.  The former Royal Manchester College of Music, now the Royal Northern College of Music, also awarded the diploma GRSM (Manchester).  The diploma awarded in London was phased out in the 1990s.  When the Royal Academy became a full college of the University of London, the GRSM, along with the non-graduate Performers' Course, was replaced by the award of the BMus (London) for all successful undergraduate students.  The Royal College of Music devised its own BMus course which (uniquely among conservatories) it was entitled by Royal Charter to award.  The other mainline British music colleges followed a similar model: Trinity College of Music awarded the GTCL graduate diploma and the Guildhall School of Music and Drama the GGSM diploma.  Like the GRSM, they have been replaced.

Royal charter: A royal charter is a formal document issued by a monarch as letters patent, granting a right or power to an individual or a body corporate.  They were, and are still, used to establish significant organisations such as cities (with municipal charters) or universities and learned societies.
