So Special

If you are looking to add some beautiful music and something special and unique to your wedding, you have found what you are looking for. Stop searching and reach out to Gretchen, now!

My fantasy of having strings play as guests arrived, while I walked down the aisle and during our cocktail hour was brought to life and then some by having Gretchen and Kerry at our wedding at a private home in Oakland this month!

Their music was stunning and flawlessly performed. They really went the extra mile to support me in planning and executing what I had dreamed of for the day! They have an amazing repertoire of modern and classic music - I was so impressed by the breadth of what they offered that I truly struggled to narrow down my song list (we started with something around 50 songs that I was excited to hear played - Gretchen had to reign us in a bit ;p). I was so tickled that Everything Is Awesome was int their repertoire and they happily indulged me by playing it a second time, when I missed it being played while we took family photos. They also exceeded my expectations in their composing of a song that I wanted for my processional, but was not in their repertoire.

Not only are they musically wonderful, they are kind, clear and prompt communicators and very organized, which made the whole process a pleasure. My parents helped me plan my wedding and Gretchen and Kerry personally made each of us feel special and appreciated, and made my new husband and I feel celebrated and cared for before, during (Gretchen saved the day with a pair of nail clippers when the groom forgot to clip his nails before arriving to the venue ;P) and in the weeks since the wedding - they really do it all!

If I lived in the area, I would find excuses to hire them again and again, in a heartbeat!

The Best String Ensemble in Town!

It was such a joy and pleasure to have Musical Heart Strings play at our wedding. Gretchen (our main contact) was so lovely to work with, easy to talk to, and incredibly flexible.

It was so special to see my husband play his dad's favorite piece of classical music on trumpet with the string trio during the ceremony and to watch my 4 year-old jam away with them (they played his favorite music and gave him a foot percussion instrument to use!). Gretchen so very patiently over the course of a few months worked with my husband to get the piece and performance just right. She and the group also arrived earlier than expected to give my husband an opportunity to practice with them. These thoughtful touches and the care that Gretchen put into our day were really, truly appreciated.

They also have the largest repertoire of any string ensemble that I've seen, so it was so fun and exciting to be able to pick the music of our day that really reflected our personalities. Gretchen, Ed, and Kerry played so beautifully on the day of -- I could hear them from where I was getting ready and it was the best backdrop to the start of a very special occasion. Thank you so much, Gretchen, Ed and Kerry for painting our wedding day so beautifully with your music!

Beyond Compare – Musical Heart Strings Made Our Wedding Truly Magical!

Working with Gretchen and Kerry of The Musical Heart Strings was one of the best decisions we made for our Tiburon wedding. We immediately wanted to work with them after seeing their website and content, and their live performance did not disappoint. They are truly phenomenal musicians! From our very first outreach, they were full of excitement and so happy to workshop unique ideas with us to make our day as special as possible.

They brought two massive highlights to our wedding that our guests are still talking about. First, they were totally open to leading our recessional, playing their instruments while walking as we exited the ceremony, which gave the entire moment a beautifully joyful and light feeling. Second, they collaborated flawlessly with our DJ for a super unique grand entrance to our reception. They played live violin and cello right along with the DJ playing Glenn Miller's "In the Mood" in the background—it was incredibly fun and really got the crowd going! Gretchen and Kerry are consummate professionals whose musical abilities are beyond compare. They set the perfect ambiance and made our day unforgettable.

Fabulous Strings

Musical Heart Strings provided music for the wedding reception I coordinated, and did a fantastic job. They were kind, professional, and so talented! They had to flex a little when reception plans changed, but they did a great job. They played a vast repertoire of music, from classic to contemporary, video game and movie theme music, to special requests from the bride and groom. I highly recommend them for your special day!

The Perfect Musical Touch for Our City Hall Wedding

Our string duo from Musical Heart Strings made our San Francisco City Hall ceremony absolutely magical. From start to finish, working with them was seamless and genuinely delightful.

Thank you so much to Gretchen and Kerry! We loved the music and we got many compliments on how it added to the ceremony.

They played Billie Eilish’s “Birds of a Feather” as the groom and officiant walked in, a custom arrangement of “God Only Knows” by the Beach Boys for the bride’s entrance (which they commissioned specifically for us), and “Married Life” from Up as our recessional. Each piece was beautifully performed and set exactly the emotional tone we wanted.

What really set them apart was their professionalism and warmth. They met with us personally before the wedding and provided a clear, helpful digital guide for selecting our songs, which made the whole process stress-free. On the day of, they arrived early, set up everything without us having to think about it, and the music flowed seamlessly throughout the ceremony.

Beyond their talent, they were simply a joy to work with. You could tell they genuinely cared about making our day special. We couldn’t recommend Musical Heartstrings more highly to any couple looking for live music at their wedding!

Photos of them from our ceremony are still with our photographer but are incoming!

Best vendor decision we made for our wedding!!!

Gretchen and Kerry were absolutely wonderful! They played for eight hours — covering both our ceremony and the entire reception — and were flawless the entire time.

They are truly exceptional musicians with an incredibly large repertoire. Choosing the music with them was so much fun — they had everything from classical pieces to pop, Disney, and even EDM. They’re detail-oriented, empathetic, and such a joy to work with.

Our guests couldn’t stop raving about the music — some were even singing along to Bohemian Rhapsody and Disney classics! The atmosphere they created was elegant, emotional, and full of life.

One of my favorite moments was when they performed “Levels” by Avicii — an EDM song they learned just for me. It was such a fun and memorable highlight that my friends are still talking about.

Hiring Musical Heart Strings was truly one of the best decisions we made for our wedding. They brought so much heart, professionalism, and joy to our day. I can’t recommend them highly enough!

Amazing! Highly recommend

Musical heart strings was Beyond incredible. They gave a personal touch to all things, including text and phone calls between us to make sure that song selections and preferences were perfect. They customized certain melodies that I wanted and executed this perfectly. I’m only sad that as the bride I didn’t get to enjoy much of their performance during ceremony seating and cocktail hour. I would recommend to all in Napa Valley or San Francisco area. They were wonderful to work with and did an excellent job.
We're all about trust. Our community relies on honest reviews to help you make those big decisions with ease.

Kerry Borgen and Gretchen Egan of Musical Heart Strings are talented musicians whose name says it all. If you're looking for a professional string ensemble that pulls at your heart strings, look no further than Musical Heart Strings. I've had the pleasure of working with Gretchen and Kerry frequently over the past several years and I'm always impressed by the unusual music selections they play that are tailored to each couple's musical tastes. They are gifted musicians who beautifully render traditional wedding songs, and delightful, adventurous souls who work with you on non-traditional music, too! They are a joy to work with and I highly recommend them. Rev. Lisa Joslen, Ceremonies of the Heart

Denise Kramer Weddings Denise Kramer Weddings Wedding Planners

Musical Heart Strings duo, Gretchen and Kerry, never cease to impress me with their wide range of music from the classics to one-of-a-kind arrangements by client request. I have worked together with them in over thirty weddings, even having a bride walk down the aisle to Rockelbel and a groom (a law enforcement officer) come in to the theme from Cops. Never caught without a smile, they seem to take pleasure in their work and bring “heart” to every event their music graces. They are always timely and professional. Clients just love them!
