A Game Changer Indeed: JDR Trochilus Harmonica

No valves-No sticking, no warming up, easier maintenance

Bonus bending-Normal bends and bends on the slide notes

Overblows and overdraws-Available for full chromatic runs or phrasing options.

New design, new experience, new track

Blues/Richter Tuning(Blue): When the slider isn't pressed, it's a traditional blues tuning. When the slider is pressed, the whole harmonica is raised by a semitone. At this time the vocal range is three octaves.

Chromatic/Solo Tuning (Yellow): It is fully tuned according to the chromatic arrangement, with a two-and-a-half-octave range, from bass do to treble so. It can play most songs without worrying about valve adhesion.

Pop Tuning(Red): When the slider isn't pressed, it's a pop tuning . Novices and 10-hole entry-level players can get started quickly. It has a complete range of three octaves, covering all semitones, and can play all repertoire.

The Trochilus is a ten-hole chromatic harmonica that took more than two years to develop.

It not only makes bending and overblowing easier than on a traditional 10-hole harmonica, but also eliminates the valve-related issues commonly found in chromatic harmonicas.

What is the relationship between the JDR Trochilus (Blues/Ritcher Tuning) and the traditional 10-hole blues harmonica?

Without the slide, it behaves exactly like a standard 10-hole diatonic — full bends and all. With the slide pressed in, you access an additional set of notes (like switching from a C harp to a Db harp instantly). You can bend just as many notes when the slide is pressed in, doubling the amount of bendable notes on the harmonica.

Phosphor bronze reed without valve

The Trochilus harmonica's blow and draw reeds are arranged in the same up-and-down arrangement as a traditional blues harmonica with no valve obstruction.

Traprzoldal shaped comb

The shape of the comb is a trapezoid design, with a short tail and ergonomic design making it more comfortable to hold.

Portable size

The Trochilus harmonica is only ½ the size of the chromatic harmonica and has a complete range.

Exceptional Autofocus Performance

The mouthpiece has a square structure, providing greater intake space to increase the volume of the harmonica.

FAQ

Q1: Does the Trochilus harmonica lose air tightness without valves?

No. Though it has no valves, its air tightness won’t be compromised. 

Q2: Why is Trochilus much smaller than ordinary chromatic harmonicas?

It only adopts a single row of mouthpiece holes, cutting its volume to half of a typical chromatic harmonica. Its dimension is 5.27 * 1.22 * 0.78 inches with a light weight of 0.28lbs.

Q3: What materials are used to make the Trochilus blues harmonica?

Its covers are crafted from 0.5mm chrome-plated copper, and sound reeds are premium phosphor bronze. The comb features a trapezoidal ergonomic short-tail shape for better grip.

Q4: What accessories come with this Trochilus harmonica set?

The package contains a Trochilus harmonica, high-grade gift box, cleaning dust cloth and detailed user introduction manual.
