Duo Aligatissimo

Prize winners of the Piadena Cremona International Chamber Music Competition and the International Don Vincenzo Vitti Chamber Music Competition, Italy.

Duo Aligatissimo was established in 2011 (formerly known as Ferro Zwio), and the members of the duo have studied chamber music with Profs. Wolfram König, Joo Ann Koh, Elisabeth Bollmann and Peter Barcaba.

The two artists, Isabella I-Sheng Zehetner und Teppei Soeda, met in Vienna, Austria. They share common tastes in music and appreciate each other’s approaches to interpreting musical pieces. In 2013, they had their first East Asia (Japan / Taiwan) concert tour, which was very successful and which led to more opportunities. Duo Aligatissimo now tours once or twice a year, performing in different venues from famous concert halls like the Taipei Zhongshan Concert Hall to small café stages. Cooperating in numerous performances, the two artists have not only accumulated considerable stage experience, but have also cultivated their understanding for music while playing together. These experiences have strongly advanced both their musical and technical development. In addition to their regular concert performances, the two artists also co-teach chamber music master classes for talented young musicians in Tokyo, Japan.

“Isabella (I-Sheng) Zehetner convinced through her brilliant play”
