Bach love was on the wane. So Dale Henderson took action: He brought the composer’s suites straight to the people, to the subways of New York.

Six years later, his method is working, with the movement growing to encompass thousands of musicians performing Bach’s music in public spaces across 150 cities and 40 countries.

On Sunday, Sept. 4, Henderson will join forces with Ghanaian American pianist William Chapman Nyaho at the Bloedel Reserve to present all three of Bach’s Sonatas for Viola da Gamba and Harpsichord.

Tickets are $30 for members and $35 for non-members and can be purchased online at www.brownpapertickets.com/event/2585028.

The doors open at 6 p.m., with the performance beginning shortly thereafter.

Weather permitting, the concert will take place outside.

Picnicking is allowed, but outside alcoholic beverages are not. There will be wine and beer available for purchase.

Described by Yo-Yo Ma as a “very gifted musician,” Henderson began studying cello when he was 5. He enjoyed regular performances as a chamber musician, soloist and orchestra cellist, and made his professional solo debut at 13 with the Buffalo Philharmonic and conductor Eiji Oue.

In 1993, at the invitation of Sir Yehudi Menuhin, Henderson attended the International Menuhin Music Academy in Gstaad, Switzerland. A graduate of the New England Conservatory of Music in Boston, Henderson took his cello to the subways of New York in 2010 in an effort to champion classical music and deliver it to a wider audience.

Nyaho studied at St. Peter’s College, Oxford University, where he graduated with a bachelor of arts degree at the Honour School of Music. He continued his piano studies at the Conservatoire de Musique de Genève, Switzerland, the Eastman School of Music where he graduated with his master of music degree, and at the University of Texas at Austin, where he received his doctor of musical arts degree.

He performs as a soloist with various orchestras, including the Moscow Chamber Orchestra and the San Francisco Chamber Orchestra.
