Sebastian Piana created a new form of Milonga which has ' hiérarchisé' the rate/rhythm and which Gardel interpreted in "Milonga LED 900", "Milonga Sentimental" and "Milonga Triste".
Piana always worked in perfect collaboration with the poet Homero Manzi with whom it composed of unforgettable waltz: "Paisaje" or "Esquinas Porteñas", and of the tangos: "De Barro" or "El Pescante".
He was the type-setter of one of the anthological tangos of the Forties and whose words were of Catulo Castillo: "Roja Tinkled".
