Carey Dubbert

Carey Dubbert

Carey Dubbert has been playing music for 65 years. Though best known for autoharp and hammered dulcimer, his other instruments have included the piano, orchestral percussion, and bassoon. He has been a featured performer and workshop leader at the California Autoharp Gathering, the Mountain Laurel Autoharp Gathering, the Willamette Valley Autoharp Gathering, the Sonoma County Folk Festival, the Occidental Center for the Arts, and the San Francisco Free Folk Festival, as well as assisting with the Northern California Autoharp Study Group. He has won the Mountain Laurel Autoharp Gathering contest and the National Hammered Dulcimer Championships in Winfield, Kansas.

Noted for his relaxed and comfortable teaching style, playing tunes is always an important part of his workshops. Participants are encouraged to achieve the sound they desire by finding techniques that work best for them.

Having grown up in Rochester, Minnesota and then graduated from the University of Minnesota, it was a quite an adventure to do graduate studies at the Manhattan School of Music. While in New York City, he played bassoon with the New York City Symphony and a big band called “The New York Brass”.

“Thanks Dad” was Carey’s first recording featuring his hammered dulcimer. Next came “One Of Mine”, a wonderfully relaxing mixture of hammered dulcimer and autoharp. On his most recent CD, “Being Home”, Carey plays autoharp and hammered dulcimer. Carey was honored to be chosen to be included on both “The Autoharp Legacy” CD and “Autoharp: Up Close and Personal” DVD.

Occidental, California, has been home to Carey and his wife for about 35 years. They have two fine cats and a varying number of chickens. Ellindale is known for her fiber arts and quilting.


Ray Choi

Ray Choi was born in Chuang Ju in South Korea in 1959. When he was a teenager he taught himself to yodel and went on to start a yodeling club and began a yodeling and singing career, winning a national competition in Korea. He found he had a natural ability for music, theory and perfect pitch, and soon taught himself guitar. In 1968 he heard his first chromaharp, and was so impressed by its sound that a few years later he got his first autoharp, teaching himself strums, finger and thumb picking.

In 1984 he followed Jane to California, where they later married, and had two children, David and Esther. Together Ray and Jane own and operate Grace Music in Tustin. After collaborating with mentor Paul Cramm, a luthier in Orange County, Ray became a luthier, building beautiful, rich resonating tones with full volume into the warm and exotic woods of his own autoharps. Currently Ray has built over 650 autoharps, each taking about 100 hours to craft. Through the years Ray has given lessons to as many as 600 students. Ray is also Music Director of his church, performing at many other churches and public events, including weddings, funerals and celebrations. Ray conducts autoharp workshops and concerts and currently has two local autoharp groups that he meets with monthly. In his spare time Ray is compiling three new books for autoharpists: one of approximately 650 hymns, and another of approximately 1000 popular, folk, religious, western and classical songs, all in authoharp tabluature, a booklet illustrating his finger techniques, and a book/DVD for beginning autoharpists.

Although Ray plays woodwind instruments, mandolin, and guitar, he lives and breathes the autoharp. “I think autoharp all the time, all day, when I wake up and when I try to sleep,” he passionately states. Over the years he has developed a new technique, dubbed “the hummingbird tremolo” because of its incredibly fast flutter of fingers across the strings, similar to the sound of a mandolin, a skill that took 1000’s of hours to perfect. In 2011,using this new skill, Ray Choi won both first place championships at both the Mountain Laurel Autoharp Gathering and the Walnut Valley International Music Festival in the same year, a feat only a few other autoharpists have ever accomplished.

Ray has sold 1000’s of Oscar Schmidt autoharp through the years and the company calls him “Mr. Autoharp.” His passion for the autoharp resonates not only through his own handcrafted instruments, but also through the intensity of his skill, passion and dedication to his students and the autoharp community as he teaches, sings, yodels, and plays the songs we’ve all come to love. Ray truly lives and breathes the autoharp!
