Brass quintet repertoire: Along with a concerted effort to commission new works for brass quintet over the last sixty years the bulk of any brass quintet's repertoire consists of arrangements of pre-existing music.  Victor Ewald's four brass quintets are the first serious attempts at establishing a repertoire for the ensemble, though they do not stand up to typical string quartet repertoire of the same and preceding eras.  The Chicago and New York Brass Quintets made sustained efforts to commission new works, and much of the original repertoire for brass quintet from the mid-20th century derives from their groundbreaking work.  In the 1960s the mantle of creating a repertoire for brass quintet was taken up by the American Brass Quintet.  But it was Canadian Brass that developed the pragmatic approach to repertoire that has set the standard.  They developed a two prong approach to performance,developing a masterpiece approach to repertoire that popularized the brass quintet as an ensemble.  Meanwhile, the ensemble has been pursuing an aggressive 45-year commissioning schedule.  Though this ensemble is seldom recognized for its achievement in the contemporary sphere, they have created well over 100 newly composed works for brass quintet.

Oja has written that, "with the 'Tonight' quintet, Bernstein once again created a masterpiece of ensemble, one that rivals the best of such moments in European opera."  Her remark echoes the earlier view of Will Crutchfield.  In his review of the 1984 studio performance of "West Side Story", which was conducted by Bernstein himself, Crutchfield wrote that the release of the recording "is above all an occasion for celebrating one of the great operas of our century.  ... This idea is hotly resisted, but the best argument for it is here on the records in the music itself.  I can see no reason why the 'Tonight' ensemble should not be compared to the quartet from "Rigoletto"."
