About 1TONE

1TONE was established and currently being run by Anton Koren who gave this instrument the name “steel tongue drum”. Since 2007 Anton has tuned a few thousands of handmade instruments.

Our perspective

Our goal is to make a fine percussion instrument with a unique sound that will leave a positive impact on it’s player and it’s environment.

We are looking for a sound that resembles the sound of a string, which always has all it’s partials (harmonics) perfectly aligned with it’s fundamental vibration. That’s why the string produces that long and “harmonious” sustain after it’s being plucked or stroke.

In our work, we try to imitate this behavior by tuning the first two overtones. The lowest partial is tuned to be one octave above the fundamental and the second one to be that octaves fifth – exactly like in a string. This is done by creating a perfectly balanced tongue with all it’s tensions in the right places.

This tuning process changes the natural metallic sound ( timbre ) of the material and so it can no longer be identified as metal by our ears. Instead the tongues sound more like strings. This is the reason that the vast majority of the steel tongue drums made today (which do not have tuned harmonics) actually sound more metallic.

We love tuning our instruments to various scales from different parts of the world, so if you are looking for a special scale or a mode that is not on our list, just ask us and we will gladly tune your instrument to it. It is also possible to tune to A=432Hz.

About the ZenCanoe

The ZenCanoe has a gentle low bell-like tone with a relaxing timbre and long lasting sustain. It is perfect for meditation sessions or yoga classes and can be a great addition to your house entrance, office, studio or workshop.

The long lasing tone of the ZenCanoe contains a “beat” in it’s vibration. This wavy sound can help us relax, meditate, or reduce stress by stimulating the activity of the low frequencies in our brain.

Each size of bell produces a different pitch. Bigger bells have lower pitch, smaller ones have a relatively higher pitch.


About the Funtone drum

The “FunTone” is the latest model of our steel tongue drum. Our premium “Pro” model is harmonically tuned having two partials ( overtones) tuned to each note.

We designed this drum to be very comfortable for playing. The form of the instrument has just the right angle for a natural wrist positioning making the playing experience effortless. This drum is very loud despite it’s small size, it can be easily heard in a busy street or while accompanied by other instruments.

After a long search for the perfect material, we have now found our favorite steel alloy. We treat the metal with carbon and nitrogen in order to make this instrument more resonant and responsive to touch, this also strengthens the body of the instrument turning the FunTone into a very durable steel tongue drum.

This tongue drum is made of two steel shells 1.5mm thick and weighs 4kg. The diameter of the FunTone is 40cm.

About the DreamHarp

This is a melodic musical instrument with a pleasant, long lasting sound.

Playing it slowly and gently, gives the instrument a therapeutic character. The low vibrations  produced from this instrument stimulate the low frequencies in our brains allowing us to alter a calm state of mind. This instrument is suitable for therapists in the fields of Music/Sound Therapy, Guided Imagery, Healing, Yoga and Meditation classes.


How to play Dream Harp?

This instrument is very easy to play, it is intuitive for anyone. The Dream harp encourages slow and relaxed playing thanks to its long sustain. In order to produce the optimal sound from the instrument, strike it softly with the mallet at the center of each tube.

Playing with an unsuitable mallet may produce an unwanted sound so please stick to our sticks..

About the MagnetBack Kalimba


Kalimba also known as Mbira, is an ancient musical instrument originating in Africa. The body of the classic instrument is made of wood, it has a number of flat metal keys connected to it and tuned to a musical scale. The Kalimba is played by plucking with the thumbs- this is why it is commonly referred to as ” Thumb Piano”.

MagnetBack Kalimba

The unique feature of this compact instrument is the powerful magnet that is located on its base allowing the sound to be amplified by any metallic object it is connected to.


This petite Kalimba will fit inside your pocket giving you the opportunity to take your music everywhere you go. It’s sound is very gentle while played “unattached” so one can remain unnoticed in a time of need, but as soon it touches a random object, the sound becomes much stronger and can be heard from far away. Experiments with different materials will lead to various sound effects.


Comes in a small metal box that can be also used as a resonating chamber.

The history of 1Tone Drums

1TONE was established by Anton Koren in 2007. The first instruments that were built under this brand name were didgeridoos. These instruments are known as “single note” instruments that can play a wide variety of overtones, hence the name 1TONE. In late 2007 Koren discovered the work of a musical instrument maker Dennis Havlena from the US. Dennis have Inspired Anton with his idea for making a tongue drum from metal. The original instrument made by Denis was constructed from an empty gas tank and had tongue shaped cuts similar to those of the original African slit drum, he called it a “Hank drum”.

In December 2007 Koren created his own version of metal slit drum, he gave it the name “steel tongue drum” which is now the most common name for this instrument.

The following year Koren teamed up with Asaf Lebovich to build the “Eclipse” drum – soon to be the first fine tuned tongue drum. The idea was to create an actual hybrid between the African tongue drum and the Caribbean steel pan- an instrument that has one or two partials tuned “inside” each note. The instrument was designed to have one bass note in it’s center resembling a membrane. By 2009 each 1TONE tongue had it’s 1st harmonic tuned inside it. This was a real breakthrough in the field making turning the steel tongue drum into a fine tuned instrument.  The production of the Eclipse drums ended in 2012 and was followed by the FunTone model.
