Aschero's numberphony ( Numerofonia in Spanish, his mother tong) is based on mathematical sciences (geometry and arithmetic), optics, acoustics and linguistics, which makes it very clear and understandable even for three-year-old children. It is a completly  inclusive and logical system that allows everyone, but everyone without exception, to read, write, interpret and create music, cultured or popular, including adults, teenagers, children and people with special needs.

In our Introduction to Music classes we are actively using numberphony material with beautiful results, we find that it reinforces motivation and calls for curiosity by connecting nature and the world around us to this new world of music.

Join our Numerofonia workshops and discover this wonderful music reading system created by Sergio Aschero.


Sergio Aschero

Sergio Aschero was born in Buenos Aires, on June 8th, 1945.
He studied in Argentina, Spain, and Italy.
He began his musical studies at the Collegium Musicum of Buenos Aires, with Guillermo Grátzer as his professor. Then, Aschero went to the Conservatorio Nacional de Música de Buenos Aires (National Conservatory of Music of Buenos Aires) and later to the Royal Conservatory of Music of Madrid, where he earned the degree of Senior Professor of Harmony and Composition. He got a PhD in Musicology at Universidad Complutense of Madrid. In 1965, he was awarded a scholarship by the Fondo Nacional de las Artes (Argentine Endowment for The Arts) acknowledged by Argentine folklore musician Leda Valladares, to carry out a musicological survey of the Chahuancos1 in the province of Salta, and a second scholarship acknowledged by professor Ljerko Spiller to conduct specialization seminars in contemporary music at Instituto Di Tella (1968).
He started his career as a theatre music composer in 1963.
At the same time, as a composer specialized in setting poetry to music, his songs were recorded, among others, by Mercedes Sosa (Miguel de Unamuno), Ana Belén (Nicolas Guillen), Rosa León (Rafael Alberti), Los Juglares (Federico García Lorca) and Los Lobos (Miguel Hernández).

His work was so much acclaimed that, after evaluating 2000 teachers and 56,000 students, the M.E.C. (Ministry of Education and Culture) certified his music system as “a positive alternative to the traditional notation”. The M.E.C. published the work Sonocolores based on the Aschero Musical System (1992), which was presented by the Minister of Education, Javier Solana, and the congresswoman Carmen Romero (wife of the Prime Minister Felipe González.)
His challenging ideas to improve the traditional music notation system were supported by, among others, the French composer Darius Milhaud, the Italian composer Luigi Nono, the Argentine composer Juan Carlos Paz, the Spanish composer Ramón Barce, the Moscow Virtuosos, the Russian conductor Vladimir Spivakov, Dr. Mario Koppers from the Faculty of Arts in Pretoria, the astrophysicist Stephen Hawking, Dr. Nicolás Oriol, Professor of Music Education at the Universidad Complutense of Madrid, and by professor Miguel del Barco, director of the Royal Conservatory of Music in Madrid.
