- 3¾ octaves overall range
- 3½ octaves chromatic range
- solid sapele soundboard and back
- traditional 5th-interval tuning
- 16/15 configuration with an 8-course super bass bridge
- reinforced with carbon fiber for stability
The D550 has the same size frame as the D500, but adds 5 more courses of strings to the super bass bridge, extending the bass range down to G2. One of our mid-sized Chromatic Series dulcimers, it combines a highly useful 3¾ range and deep, lush tone with a relatively portable body size, making it among our most popular instruments.
Working closely with our design partner, Sam Rizzetta, we developed what we're calling a "dual-density bridge system" to optimize the tonal balance across the range. In the upper register, we're using jatoba, a very dense and articulate South American tonewood, which brings out the clear, ringing bell tones of the high notes. Slightly lighter density Eastern hard maple in the mid and lower ranges facilitates a full, warm, round tone. This combination surrounds the player with a balanced blend of clarity, responsiveness, sparkle and warmth.
Starting in 2011, we began incorporating carbon fiber into the internal bracing of our Chromatic Series dulcimers, improving upon their existing reputation for excellent tuning stability. With a stiffer frame, the tuning stability has gone from excellent to truly exceptional, a benefit that any dulcimer player will appreciate wholeheartedly.
The C500 case is available separately.

The Chromatic Series
Dusty Strings Chromatic Series dulcimers are professional-caliber instruments and are widely regarded as being among the finest hammered dulcimers available. However, this does not mean you have to be a professional to play one! As a beginner, you might be amazed at how quickly you make progress on an instrument that sounds fantastic and is well-made and satisfying to play. Regardless of your experience level, we think you’ll find the sophisticated tone and detailed craftsmanship of the Chromatic Series dulcimers to be well worth the investment.
The tuning scheme is a variation of traditional 5th-interval tuning, where the chromatic notes either replace duplicated notes or are added via extra bridges. We’ve found that it’s no different for a beginner to learn on one of our chromatic instruments than it is to learn on a more basic traditional instrument. More advanced players who are accustomed to traditional tuning will find it easy to adapt and will be delighted by the increased versatility of having access to all the sharps and flats. The chromatic capability opens the doors to musical styles such as classical, ragtime, bluegrass, jazz and rock.
Designed in collaboration with Sam Rizzetta, a highly respected inventor, builder and player of hammered dulcimers since the 1960s, these instruments have his signature asymmetrical design, which places the treble bridge perpendicular to the strings for ease of playing. The internal bracing system is more elaborate and sophisticated than our other models and, combined with the all-solid-wood construction, gives our chromatic dulcimers a resonance, clarity, and depth of tone that is unrivaled.
For the ultimate expressive instrument, we highly recommend the optional damper system. Dampers allow the player to stop the strings from ringing by pressing on a foot pedal, and can be used very effectively to support even more nuanced playing, complex arrangements and interesting voicings. The Chromatic Series dulcimers are now being built with pre-drilled and capped damper installation holes, which will streamline the installation of a damper system whenever it is desired.
The single sound hole is decorated with a hand-carved maple leaf insert, a signature feature of our chromatic line. Contrasting solid-wood binding and delicate multi-layered veneers called purfling add a professional finish detail to the soundboard.

Tuning & Specifications
The D550 has three and a half octaves of fully chromatic range. The lowest note is the G two octaves below middle C. It is laid out in a 16/15/8 configuration, meaning that there are 16 courses of strings on the treble bridge, 15 courses on the bass bridge, and an 8-course super bass bridge on the left, which provides the lower half-octave as well as the additional chromatic notes that aren't normally present in the dulcimer tuning scheme. The overall range is G2 to E6. The chromatic range is C3 to E6.
