tirasse
French composer
Definition
A coupler that connects the pedal division to a manual, allowing pedal passages to speak with the full weight of a manual division. Franck's bass lines often require the Great-to-Pedal tirasse.
Interpretive Guidance
The tirasse must be used whenever Franck writes sustained pedal bass notes beneath full manual texture — which is nearly everywhere. Without it, the bass will be inaudible against the manuals. Ensure the pedal touch is legato and the bass line is as melodically shaped as the manuals, since Franck's bass lines are true melodic voices, not merely harmonic support.
