Our History

Harmony Studios is family owned and operated. Aubrey and Erwin Rocha first opened the doors of Harmony Studios in April of 2014 after many years of teaching and performing in the Orange County and Los Angeles Counties. Harmony Studios was named after a song that was written and recorded with students who attended "Rock The Summer Music Camp", an annual music camp Aubrey and Erwin began as an outreach to expose less fortunate children to the gift of music.

Erwin Rocha

Erwin recorded his first album at the age of 13, which led to him winning two Latin Chin de Plata's (Latin Grammy’s) and sharing the stage with the likes of Gloria Estefan, Celia Cruz & Tito Puentes to name a few. After attending the Miami Conservatory of Music, Erwin moved to California and became a highly sought after studio vocalist for some of top studios in Los Angeles. It was then that he began to learn from some of the biggest music producers in the industry. Over the past decade, Erwin has focused on his passion of developing artists & producing records under his independent label RediRecords/Volsa Entertainment.

When he isn’t working on his music or voice coaching, he enjoys leading worship, mentoring youth throughout the community and being with his son Samuel.

Aubrey Rocha

She recorded her first album of original music by the age of eighteen and released her second album “Unspoken” in 2014.

Meet the Instructors

Paige Williams

Voice, Piano, Ukulele, Guitar & Cello

Born in San Antonio, Texas, Paige has traveled the world experiencing countless cultures and music styles. Cello was Paige’s first learned instrument, but her passion and drive quickly led to her studying Piano, Guitar, Ukulele and ultimately graduating Magna Cum Laude from Georgia State University with her Vocal Performance degree. Meanwhile, Paige’s voice quickly took the world by storm, winning the “Georgia State Idol” Singing Competition, placing second in the “Le Florilège” vocal competition in Paris, and singing in the supporting choir for Andrea Bocelli. In 2017, Paige left her busy life of teaching, playing weekly concerts with her band and recording her EP of original music to make her dream of living in California a reality. When she isn’t teaching lessons at Harmony, Paige can be found singing her heart out and promoting her EP “From Here to Where” at her shows around Los Angeles, cheering loudly in the front row of her music students school plays and sports games, or hanging with her adorable pup, Moose.

Elizabeth Dobbin

Viola, Violin & Voice

Having grown up in a very musical household in her hometown of Hillsboro, Oregon, Elizabeth quickly took to her surroundings. She holds a B.A. in Music Performance from Concordia University in Irvine, CA and has studied all types of music including classical, jazz and worship in her 16 years of playing the viola, violin and voice. Since completing her undergraduate degree, Liz has continued her education and is currently working towards completing the Suzuki Teacher Training program. Liz leads an active career as an orchestral musician, performer, and has recorded on supporting tracks for multiple albums. When Elizabeth isn't teaching at Harmony, she is working on her other passion and is currently writing the manuscript to her second novel.

Cole Zwickl

Guitar & Ukulele

Cole was thirteen years old when his parents purchased his first guitar at a local pawnshop in Long Beach. Eager to learn, Cole rummaged YouTube for as much information as he could get his hands on and his newfound love for music and playing guitar stuck. He went on to study worship arts at Hope International University and has led and served as youth worship director at churches throughout Orange County. Cole has recorded with the Christian band, “The Procession” and played a very memorable concert at Hume Lake. Since Cole started out as a “self-taught” guitarist, he is enthusiastic about removing the veil that makes the ability to play music seem like a “superpower or foreign language” and equipping students with the tools to grow independently as musicians. When Cole isn’t jamming on the guitar or teaching, he loves writing music, playing and following sports (Go Angels!) and going to concerts.


PJ Frazier

Drum & Percussion

A native of Orange County, PJ discovered his passion for drumming at an early age. With over a decade of studying his instrument and performing in award-winning bands at iconic venues such as The House of Blues in Los Angeles, PJ has a wealth of knowledge on what it takes to thrive as a gigging drummer. He greatly enjoys getting the opportunity to influence and work with the next generation of drummers. When PJ is not at Harmony, you can find him mountain biking, working towards his college degree or writing and recording with his band, “The Cuff” who is set to release their first album in 2018.

Cameron Haugen

Guitar, Bass & Ukulele

Cameron took his first guitar lesson when he was nine years old and it wasn’t long after that he picked up the ukulele, bass and found his voice as a singer. Since then, he’s been the lead guitarist in several bands playing styles ranging from rock, acoustic singer-songwriter, alternative, country and grunge. Cameron developed a heart for worship at an early age and has served and led on Eastside Christian’s “NextGen” worship for the past four years. Cameron’s favorite thing about teaching is the moment when everything clicks for the student. When the mystery of music starts inspiring curiosity instead of confusion, and the student can start making it their own. When Cameron isn’t working towards his degree in music from Fullerton College or teaching, he is reading, songwriting and serving at his church.

Luke Thomas

Guitar, Ukulele, Bass & Music Production

Luke Thomas started playing guitar when Nirvana first hit the airwaves in the early Nineties. Since then, he's grown up on a steady diet of Stevie Ray Vaughan, Jimi Hendrix, Metallica and Wes Montgomery. Luke has played every style imaginable from bluegrass to metal, and worked as a session musician and touring guitarist. He holds a degree in Jazz Studies from University of Wisconsin and has played in many bands since his move to California, including afro-beat and reggae bands, experimental/progressive rock outfit eEnik, rock band SuperNaked, and his current electric jazz project The Jazz Martyrs. Luke actively performs as a solo and classical guitarist and has been teaching all levels and styles for over fifteen years. Many of his students have gone on to successful music careers and attended Musicians Institute, LA College of Music, and Berklee College of Music.
