The Classical Marimba League (CML) accomplishes its mission through the promotion of new classical music composed by the most creative emerging talents in the arts today.

As the majority of the marimba's standard repertoire has been composed in the past 70 years, there is a wide stylistic gap in the music literature for the instrument.  In comparison to the piano or violin, each having developed repertoire going as far back as the 1600's, the marimba has been at a significant disadvantage in the classical concert arena due to the void of comparable music from the earlier time periods.

The CML holds an annual Composition Competition to inspire new works composed for the marimba.  This endeavor has as its primary purpose to stimulate a rebirth of these styles of music for the instrument, aimed at augmenting a repertoire suited for the classical concert stage and music competition. 

The CML also holds the Marimba Artist Competition for marimba performers to showcase their talents.
