Originally entitled 'Tonight', Perfidia came into its own when given the Glenn Miller treatment, as a fabulous vocal showcase for the Modernaires. Our arrangement is true to the original, except that we give the vocal chorus to the trombone section as a feature. This chart has the correct Miller voiced saxes, the 'surprise' key change , the blend from brass to reed behind the cameo bass solo near the end, and all the written dynamics to help create the authentic sound.
