Sigma Project

Summam indicabimus signo Σ. With this statement, one of the most important mathematicians in history, Léonard Euler, inaugurated in 1755 the use of the capital letter sigma (eighteenth of the Greek alphabet) as a sum symbol. Since then, Sigma represents the sum of a finite or infinite series of elements.

SIGMA Project is more than a saxophone quartet. It is the realization of a wish came true, an essential vehicle for instrumental music in the 21st century. Just as the string quartet was the instrument par excellence for art music in past centuries, SIGMA Project claims this role in the 21st century for the saxophone quartet.

SIGMA Project has its own record label, Sigmarecords, and has edited the CD Utopías: New Music for Saxophone Quartet and the DVD The Music for saxophone by Félix Ibarrondo. Additionally, they have recorded for the BBVA Foundation (José Manuel López López and Gerardo Gombau monographs), Orpheus Classical (María Eugenia Luc monograph), Casa Velázquez-Académie de France in Madrid (Víctor Ibarra monograph) and, invited by the German Foundation Ernst Von Siemens Musikstiftung and with the label Col Legno, the Simone Movio monograph.

SIGMA Project’s work is supported by the Instituto Nacional de las Artes Escénicas y de la Música, the Etxepare Basque Institute of the Basque Government and the German Foundation Ernst Von Siemens Musikstiftung.

SIGMA Project performs with SELMER instruments and VANDOREN accessories, and the technical assistance is provided by PUNTO REP.
