Congratulations on your piece.
Below, a historical example of the hoquetus technique: 'Hoquetus David' by Guillaume de Machaut (14th century), vocal version. A beautiful interpretation and a video in which one can visualise the alternation specific to this technique. There are also many instrumental versions.
'On ne devrait jamais quitter Montauban' (Fernand Naudin).
