Unda Maris 8 Filippo Sorcinelli

"From the Latin 'wave of the sea,' it refers to a particular stop of the organ. It is a 'soul' stop. It consists in two equal pipes but with different intonation. By making them play simultaneously, the phase displacement between the two frequencies produces a particular physical phenomenon called 'beating,' which generates the specific 'swaying' and flute-like effect of the sound. Unda Maris is similar to the human voice stop, but, unlike the latter, its sound is produced by slower beats." (A note from the brand.)
