Pianists Stephanie Ho and Saar Ahuvia collaborate as DUO Stephanie and Saar in performances noted for their artistic versatility, elegance and intellectual curiosity.

They appear with the Arizona Bach Festival performing Bach’s “Art of the Fugue” for piano four hands, their newly released CD.

As probing recording artists, the duo explores repertoire with concomitant classical and contemporary sensibilities. Beethoven Dialogues, their 2014 album featuring Beethoven Quartets Op. 18 Nos. 1, 4 and 6 in rarely heard four hand arrangements, was performed in its entirety at New York City’s (le) poisson rouge and chosen as Album of the Week on WQXR. Bach Crossings, the duo’s 2012 album featuring György Kurtág’s illuminating transcriptions of Bach, continues to receive acclaim. International Piano Magazine states, “It is clear from the precision and elegant phrasing on this disc that this is a tight partnership between pianists who have developed an implicit understanding of each other’s musicality.” The New York Times praised their “beautifully understated performances” of selections from the disc.

Highlights from their eclectic programming include a jazz-inspired concert at the South Miami-Dade Cultural Arts Center featuring the world premiere of Fantasia de Très Mundos by Cuban-American jazz pianist Martin Bejerano. In celebrating the 100th anniversary of Igor Stravinsky’s Rite of Spring, DUO Stephanie and Saar toured Rite in four-hand, two-piano and mixed ensemble arrangements. Multiple collaborations with Michael Linville and the New World Symphony Percussion Consort featured Linville’s own arrangement of Igor Stravinsky’s Petrouchka and André Boucourechliev’s aleatoric fantasy piece Archipel I. The duo takes special pride in a performance at the residence of the United States Ambassador in Berlin, Germany, featuring works by Henry Martin (US), Avner Dorman (Israel) and Felix Mendelssohn.

DUO Stephanie and Saar are the artistic directors of Makrokosmos Project, a new music festival in Portland, Oregon dedicated to American music and performances by Oregon-based performers and composers. The 2015 inaugural festival featured standing-room performances of George Crumb’s Makrokosmos I & II and music by Kenji Bunch and David Crumb. Oregon Arts Watch frankly states “It was one of 2015’s peak Oregon musical moments.”

While pursuing graduate studies at the Peabody Institute of the Johns Hopkins University, Stephanie and Saar were inspired by Leon Fleisher to explore the Beethoven string quartets in a duo piano setting. Saar Ahuvia, a native of Israel, studied at Israel’s Tel Aviv Academy and Switzerland’s Schaufhausen Conservatory before coming to the United States to pursue a Graduate Performance Diploma with Leon Fleisher at Peabody Institute. Stephanie Ho, of Taiwanese descent, grew up in Portland, Oregon before obtaining degrees from Oberlin College and Northwestern University. She received a Graduate Performance Diploma from Peabody Institute, under the direction of Julian Martin. Stephanie and Saar, who are married to each other, reside in New York City.
