As the Maid of Honor, I’ve had a front-row seat to every dream, detail, and Pinterest board leading up to my best friend’s wedding. But nothing prepared me for the moment the ceremony began—and the music started to play. The incredibly talented cellist from String Theory transformed the atmosphere into something truly magical.
From the very first note, it was clear we were in for something special. The cello’s rich, warm tone floated through the vineyard, setting the mood with an elegance that gave everyone chills (and maybe a few early tears). The way she played—so soulfully and with such emotion—added a depth to the ceremony that words really can’t describe.
She performed everything from our playlist with seamless transitions. Watching the bride walk down the aisle to that beautiful, resonant sound was one of the most emotional and cinematic moments of the entire day.
What I appreciated most, as someone helping coordinate a lot of the moving parts, was her professionalism and calm presence. She arrived early, was incredibly kind, and worked closely with the planner to ensure everything was timed perfectly.
If you’re considering live music for your wedding ceremony, do yourself a favor and book the cellist from String Theory. She didn’t just play music—she helped create a moment we’ll all remember forever.

The music for my daughter's wedding was stunning. Allison Marshall was so easy to work with. Her suggestions were so helpful and even added two pieces for a very nominal fee that weren't in the string trio repertoire. I highly recommend String Theory!

Woking with String Theory was so incredible! It had always been my dream to have live strings at my ceremony and they made it happen. Working with Allison was such a pleasure. She got back in contact with me super fast and helped me plan out all of the pieces the musicians would play. I was extra appreciative of them when planning went bonkers after Helene went through my hometown and I wasn't able to contact them about when to play and the schedule of the day. I am so thankful for their professionalism and beautiful music. You guys made everyone cry, especially my dad which is a huge bonus! Thank you all so so much!

String Theory Music was incredible - we used them for our ceremony and cocktail hour and I cannot begin to express how perfect they were. The musicians nailed the music, everyone complimented them and they even learned my aisle song (Across the Stars) and performed it perfectly! Allison is professional, quick to respond, and all around a perfect vendor. If you are considering strings for your wedding, I would HIGHLY recommend this group!

I was introduced by recommendation to Allison, the String Theory Music Coordinator, through one of the late owners of Castle Otttis in St. Augustine, FL. It was such a sincere pleasure working with her attributes of professionalism, humble partnership, prompt responsiveness, and genuine smile orchestrated amidst our fairytale dreams that were brought to life at our wedding. The violin and cello duet yielded echoes across time that our still heard in our cherished memories to date. Allison and her team were very accommodating in learning new Celtic music and recomposing a Vivaldi classic, in addition to the vast repertoire that was already available. String Theory is highly recommended for any venue that is ready to be enchanted with tunes that will make dreams come true!

We used String Theory Music for our wedding ceremony on December 3rd and I am so happy that we did! My husband was a little wary about not just using the DJ for our ceremony, but ended up being so happy that we chose them instead! We did a violin and cello duet and they were absolutely incredible! Allison Marshall was always super responsive to my emails and made great suggestions for songs when we needed some! We requested a song from them that was not on their list and they had no issue learning it for us. We did a first look before the ceremony and could hear them practicing in the background which was absolutely incredible. While the ceremony was beautiful, I kind of blacked out so I am glad we were able to enjoy them on our own during the first look. An added bonus that I was not expecting! Overall, we definitely recommend String Theory Music! It elevated our ceremony to a whole new level and made it even more special and beautiful! Our guests had nothing but great things to say about them!

She is totally professional and personal. Allison made me feel as if ours was the only wedding she was playing. Personalized, efficient service and delivery is what you get as well as beautiful music. The music gave our daughter’s wedding that finishing touch which perfected her special day. I will use Allison again!!

Incredible. I would give 100 stars if I could! We booked String Theory Music to play during our wedding ceremony this past Saturday. I cannot say enough good things about them.
From the very first interaction with Allison, she was so friendly, personable, and easy to work with. She took the time to answer all of my questions and gave her professional input, which was invaluable to us.
I found their prices to be very reasonable and fair for the services and level of quality they provide. They have an extensive song repertoire, but if the songs you want aren't on the list, they even offer commissioned arrangements at a very reasonable rate and will learn the new songs for you!
String Theory has violinists, cello players, but I really wanted a piano player too, so I booked a piano player to accompany them through another website. Allison took point on managing interactions between the musicians, and musicians collaborated together while needing very minimal direction and input from me, so they made the process very easy for me. When it all came together on my wedding day, we were absolutely blown away. They don't simply just play notes, they play it with so much passion and emotion. Their professionalism, artistry, and dedication to their craft is evident. It was the highlight of our whole wedding!
If you are on the fence about booking them, please, just go ahead and do yourselves the biggest favor and just DO IT! You will never be disappointed!!

We booked a String Quartet for our wedding day through String Theory. Allison was such a pleasure to speak to and work with through the process. She didn’t hesitate to add songs I wanted that weren’t on the list for the ceremony music, such as “Sky Full of Stars” for my entrance and the “Jurassic Park” theme song for my husbands. We are very honored to have had her and the other musicians be a part of our wedding day, they were perfect. We will have beautiful memories of our music for years to come because of the performance of String Theory. They will add another part of love to your wedding day with their beautiful music! There is nothing else like the feeling that live instruments can add to your wedding day, it will give you goosebumps. Thank you String Theory from the bottom of our hearts!

I highly recommend string theory. We had a cello.player and I wish I remembered her name. Our day was crazy with a storm all around us. We had to pull the service off the beach. Our cello played froze her fingers and never complained. She was positive and didn't add any stress to our crazy day. Her talent was supreme. It really added atmosphere and a personal touch. I was mother of the bride and it was my gift to my daughter

What a beautiful addition to our ceremony String Theory was! We originally had a friend playing acoustic music for us but I worked multiple weddings with this vendor and they were so talented we decided we had to hire them if they had our date available (July 3rd, 2022) We were so thankful they did and they were so accommodating. We chose a string trio. We were only particular about a few songs for the processional but otherwise kept song choices in their hands. We are still receiving compliments about how beautiful it was. It added an extra step of elegance to our ceremony which is exactly what we wanted before the "party" part of the wedding. They arrived promptly on time and played for half an hour before the ceremony. We can't thank them enough for being apart of our day and making it even more special.

All I can say is wow! I splurged a little on a solo cellist for my wedding ceremony and cocktail hour and it was incredible. Completely icing on the cake of our perfect little wedding by the lake at the Manor at 12 Oaks Farm. I can’t recommend these guys enough. Talented, professional, and so helpful with choosing music (we did a mix of classical and modern)! 12/10 Thank you!

So we had lined up music that fell through the week of our wedding, enter the INCREDIBLE String Theory! Allison and her musicians truly saved our day. She was quick to respond and so understanding of the situation. We were able to have all the music we wanted for our ceremony and it sounded amazing! At the beginning of my ceremony I was standing at the top of a staircase, listening to the beautiful music float up to me and I almost started crying. I’m not a crier! Thank you String Theory for making our day special!

We had String Theory Music play all the music for our morning wedding and reception and it was perfect! I had contacted Allison as soon as we were in contract with a special request. We wanted a classical piece when walking down the aisle that was not in their repertoire. She was wonderful to work with and extremely accommodating. We asked them if they could do it and she made it happen for a nominal amount. It was perfect!! If I could give them 10 stars, I would. If you need musicians for any event, I would use String Theory Music if possible…I highly recommend them!!

String Theory is the best vendor we had at our wedding. Allison is so professional, talented, and nice. They were so easy to work with and I felt like we weren’t going to have to worry because they had their act together. During a wedding, I have learned that you have the groups that you have concerns about, String Theory is the opposite... you don’t have to worry, they’ll exceed your expectations...they’re amazing!

Allison and her team were able to add a special touch to our wedding! We had an afternoon tea wedding and having them play was the perfect addition because having a DJ during the ceremony and cocktail hour did not seem fitting. They played a special request song of “La Vie En Rose” as I walked down the aisle and it was played wonderfully. Allison was very easy to work with and I cannot recommend their services enough.

What an honor it was to have these musicians play at our wedding! It's been just over a year since we got married and our family and friends still talk about the music. These ladies are top notch musicians and people. Allison is so kind and easy to work with. She was patient with all of our questions (and there were many) and is very responsive. She really made me feel like mine was the only wedding that mattered and gave me her undivided attention throughout the process. She really cares and it shows. 5 stars just doesn't seem like enough to express our appreciation!

It has been a few years since my husband and I got married at the San Marco Preservation Hall. The small chapel was the perfect setting for the violin & cello to play music for our wedding. Using String Theory Music was a no-brainer for us since we had attended more than one wedding where they performed and always loved what their music brought to the environment. Allison is always a pleasure to speak with and it is obvious that she loves what she does. We most definitely recommend them to anyone who is looking for talented, beautiful people to play music for their wedding!

String Theory Music played during our ceremony this past August and we have nothing but nice things to say about this company. They were so accommodating with our last minute decisions and the songs we wanted. They were so helpful during the whole process and very responsive. Our ceremony took place outside in a garden and the violin and cello were the perfect elegant, romantic touch to our wedding. We would recommend this company to anyone looking for reliable vendors and great music.

Allison Marshall is a dedicated, professional violinist. She has performed at the Castle Otttis numerous times.
In addition to being a very accomplished musician, Allison is incredibly patient and accomodating when an event at the castle is delayed due to late guest arrivals.
This past Saturday, Oct 3, 2015, I observed Ms. Marshall playing over two hours without surcease. She is simply amazing.
What seperates her from the average player is that she really cares about the experience of her clients.
I have been involved in music on a professional level for 40 years. Allison Marshall is a gem.

Having live string music at our event was seriously one of the best decisions we made regarding our wedding! It's an element that is often overlooked but added just the right touch and ambiance that we were looking for!
