'Can you make me a cello A string?'

The answer was anything but simple but that chance remark led to the creation of Larsen Strings. The first Larsen cello A was successfully delivered from the Larsen family garage and the Larsen family of strings began to grow along with the realisation that:

Although some of the best things happen by chance we can make them truly remarkable by design.

At Larsen Strings we develop, produce and market strings of the finest musical quality for bowed string instruments.

Strings for Violin, Viola & Cello

A thank you from us. We’ve been looking through our advertisements over the years and how the product range has grown. Some little steps and some massive leaps reaching right back to that Original A for cello. It’s not just our products, it’s a community of like-minded people here at Sønderborg and way beyond with friends old and new around the world. So a big thank you to all of you for joining us on the journey.

The Stradivari Challenge

‘Chaconne’ Stradivarius (1725) versus ‘ex-Hämmerle’ Stradivarius (1709)
Il Cannone® for Violin with both instruments played by Rainer Honeck, Concertmaster, Vienna Philharmonic Orchestra. Laurits Th. Larsen visits Vienna and talks us through a Stradivari challenge at Marcel Richters’ studio. Please view and see and hear the results.

Virtuoso® for Viola

With the development of our Virtuoso Viola strings the focus has been upon creating a new offering for viola D, G and C, built upon the firm foundations of our tried and trusted A. Now also available as Medium Extra Long.

‘Finding a balance of qualities to complement and mutually enhance something old with something new.’

Viola Virtuoso Extra Long

Il Cannone® for Violin

Designed to bring out the best in your violin, Il Cannone individual strings and sets are available as two versions. The Medium variant has a more moderate tension with an open, colourful, projecting, richer and powerful sound whilst the Soloist brings a fuller tone, with even more presence and focus. Rusanda Panfili performs with Il Cannone.
