Fantasia Latina was commissioned by Band member Neil Tischler in celebration of his 48 years with the Concord Band, and is based on four Latin dance styles: Tango, Danzon, Songo and Samba. The extended introduction is intended to introduce idiomatic rhythms and motives that are common to the various styles such as montuno and 2-3 clave, etc. In each style there are unexpected rhythmic and harmonic twists intended to keep the performer and listener from settling into a “groove.” For example, there might be an extra measure in a phrase or a very brief harmonic modulation in harmony.
