Apertures (sound holes) in stringed musical instruments have been studied, experimented with, and designed for a variety of acoustic functions and characteristics. While a sound hole’s size, shape, and position certainly influence tone and volume, its appearance is what catches the eye and creates a kind of identity.
Many manufactured autoharps have simple, round sound holes while a few have no sound holes at all. Some luthier built autoharps have distinctive sound hole designs that identify their brand and are even trademarked.
I attempt to make each of my instruments unique. The sound hole treatment is one way I have of making an instrument visually distinctive while at the same time drawing attention to the fact that the instrument was custom made. I enjoy working with my customers in choosing a cut out shape, a laser cut rosette, or a custom inlay of their personal design.
A musician from Tennessee recently commissioned this custom autoharp with several features that, to me, are very similar to the fifteen chord Oscar Schmidt and ChromaHarp models of the past. Over the years those A style chromatic models with their round sound holes, fifteen chord bars in two rows, and laminated soundboards underwent many improvements by their manufacturers. This musician seems to favor that style of instrument and was able to specify several construction, setup, and cosmetic improvements to suit his preferences and playing style.
Most of my builds have been set up for playing in the area above the chord bars with the high treble strings unobstructed by the chord bar covers. This chord set is positioned closer to the tuning pins to permit play below the chord bars at the anchor end. Many of the old OS A models were arranged this way until playing the instrument upright became common and the bar set was moved south by their owners or the factories. This instrument is designed to be played on the musician’s lap with the left hand at the chords and the right hand playing near the anchor bridge.
The old A models chord bars and buttons were 5/16 inches wide. I reduced these bars to a 1/4 inch width to narrow the array while leaving the buttons wide enough as to not require caps. The maple buttons are of a similar style to the older fifteen chord ‘harps and the chords are selected and arranged to the musician’s preference. He prefers a higher action (the height of the felt above the strings) for more vigorous chording. I set the travel high as requested but included extra self-sticking felt strips for under the covers should he choose to adjust the bars lower.
The modern improvements in the construction of this instrument include a solid spruce soundboard with tuned bracing, a one piece laminated frame, and quiet chord bars mounted on Delrin and steel pin combs. The chord bars, covers, side veneer, bridges, and tailpiece are made of African mahogany that has been stained dark brown. The musician requested that I not apply note labels under the tuning pins so I included a wooden tuning strip/duster that can be positioned under the strings to aid tuning.
A custom built autoharp such as this can be built with the preferred features and options that improve playability and appearance. Sometimes it comes with a surprise: as the owner noted, “I was in shock at how light it is!”.
I have recently located a source of laser cut ornaments in a variety of subjects. Most are too large to inlay as a sound hole rosette but with many of them, I can trim away the bordering areas for a good fit.
Here is a new custom thirty-six string chromatic autoharp. My standard, one piece pinblock frame features a spruce sound board, laminate back, and 3/16 inch thick walnut veneered sides. Matching walnut was also used for the brass rod-capped bridges, tail piece, chord bar covers, bridges and chord bar covers.
The fifteen chord bars are made of curly maple. The contrasting buttons are capped with walnut.
As a landlocked luthier here in Ohio, I truly miss the ocean. Marsha and I have lived in a coastal town on the Great Barrier Reef. We have wandered beaches in Florida, Cape Cod, Oregon, Nova Scotia, Iceland, and Ireland. We even spent two months at sea working on a container ship that crossed both Tropics and the Equator. With only some photos and a smattering of shells to sustain our fading memories, I sometimes regret leaving those experiences behind for life in the flatlands.
This thirty-seven string instrument has twelve chord bars shaped like waves. The three rows of buttons resemble white caps. Bridges, chord bar holders, tail cover, and side trim are made of curly maple dyed bright blue to show an iridescent, wave like grain.
A laser cut rosette adorns the sound hole and bare footprints cross the sandy colored solid spruce soundboard.
The laminated back has been painted bright blue using netting as a stencil. Captured in this fish net is a colorful jellyfish soundhole.
Here is a new custom thirty-seven string chromatic autoharp that I built for a beginning autoharp musician here in Ohio. She plans to play worship and folk music to accompany herself and other vocalists. Because she resides within easy driving distance to Darke County, she and her husband could visit, view the many features and options available, and order the special instrument that is to be a birthday gift from her family.
I always try to make each of my instruments unique so that my clients have a special instrument unlike any other. Of course there are constraints like scale, setup, and structure, but I like to give folks choices. This musician chose a western red cedar soundboard, maple chord bars, and curly cherry for the bridges, bar holders, buttons, and side trim.
A weeping heart was chosen for the sound hole. I made this by inlaying a 1/8″ thick cherry heart shape into the 1/4″ thick soundboard and then removing the inner heart shape leaving a 1/8″ wide cherry border.
The fifteen maple chord bars feature cherry buttons with the lateral dishing (rather than longitudinal dishing) preferred by the player. They move on #6 steel pins set into Delrin bases. The chord felt is yet uncut pending the player’s preferences.
Structurally, this A style autoharp is built with a one piece laminated pinblock frame and a 1/4″ thick laminated birch back. Lately, I have been routing away unnecessary areas inside the frame to increase the interior volume. This, along with some tuned bracing, improves tone and volume.
Hex screws are components of autoharp fine tuners. They are adjusted with some form of a hex key that is usually supplied with the assembly. This necessary implement is usually stored in the case, pick bag, or somewhere in that room you just walked into but forgot why.
…………..where it’s right at hand for quick tuning touch ups.
Many autoharps, especially manufactured ones, have decals, stickers, or note labels to designate the pitch of each string. These are unsightly and mostly unnecessary once the autoharp has attained a stable tuning. Some musicians convert their instruments to an alternative tuning such as a diatonic setup with a completely different tuning schedule that is no longer supported by the existing labels.
I printed a tuning chart that I glued to a thin strip of wood. This can be slipped under the strings when needed as a reference for tuning each string.
On the reverse side of the tuning strip is red felt. It prevents the wooden strip from scratching the soundboard and doubles as a convenient tool to remove dust under the strings.
I recently completed is this thirty-seven string diatonic autoharp in the single key of A. I built it for ourselves because Marsha and I are trying to sing along with our instruments more and find that the key of A is a comfortable range for our voices. Being a single key diatonic, it has paired string courses in the middle octave and only the notes needed for chords in the key of A. This produces a very rich and full tone that works nicely for strumming accompaniment and playing melody.
Fifteen chords are arranged in a “Bowers” type setup with major chords in the center row, sevenths in the top row, and minors in the bottom row. This familiar arrangement is in place on all of Marsha’s instruments and permits a sort of “motor memory” to kick in when she changes from one autoharp to another, even if in different keys. Seven of the chords are “color chords” for enhanced arrangements.
The instrument has a 1/4 inch thick solid spruce soundboard. The one piece frame is laminated maple pinblock with a laminated maple back. The side veneer, end cover, and chord bar covers are made of curly maple. Chord bars are maple with alternate bars painted black. Black tuning pins, bridges, Schreiber fine tuners, and purfling complete the black/white motif.
My most recent instrument is this custom chromatic autoharp commissioned by a musician here in Ohio.
The twenty-one maple chord bars are capped with walnut buttons and are mounted upon combs made of #6 bridge pins and Delrin bases. Just to be different, I kinda hybridized the chord bar covers by making a shell out of walnut and very thin birch plywood. Its top surface is veneered with sequence-matched walnut burl. There is no distinct advantage for making it this way but the larger areas of felt damping on the underside seem to make the chord bars quieter.
The side trim and bridges are walnut.
I recently completed and delivered this commissioned instrument to a musician in New York state. After the initial contact and much discussion by e-mail, the entire process required only three months. The wait probably seemed longer to the musician anxious to receive his first luthier built autoharp but its completion was well within my usual two to five month time estimate.
The chord bars, bridges, side veneer, chord bar covers, and tail cover are made of African mahogany stained with Minwax red mahogany oil stain. The chord bar covers, chord buttons, and tail cover are capped with curly maple finished natural. The soundboard is spruce, the back is maple veneer, and everything is finished with up to six coats of semi-gloss Deft lacquer.
The Schreiber electromagnetic pickup is specially wound for this thirty-seven string array and is fastened underneath the chord bars by metal tabs that fit in slots on the underside of the Delrin chord bar combs. A small length of coax is routed through the inside of the instrument to a 1/4″ jack.
Many of my autoharps are shipped out of state and abroad to musicians who will likely want to experiment with alternative chords or attend to future DIY adjustments and repairs. For this I include some extra blank felted chord bars, extra chord felt, self adhesive under cover felt, and extra springs. The wrapper from the custom string set will help them order the proper strings when it becomes necessary and a laminated strip indicates the tuning of each string. Also included is the allen wrench that comes with the fine tuners and a new star tipped T-wrench.
The latest from here at Fretnot Laboratories is this custom thirty-seven string, fifteen bar diatonic in the keys of G and D. It features Daigle fine tuners, two lock bars, flat chord bar buttons, and five extra blank chord bars for future substitutions. A custom oval rosette was fashioned using walnut burl and plastic white-black-white purfling. Walnut burl also trims the tops of the chord bar covers and the tail end cover.
