Harness your creativity and let your imagination run wild with an  mk Pro Low Whistle . It is humble, elegant, capable, timeless and limitless. It can be an instrument of togetherness, connection, expression & celebration, or of solitude, meditation & healing. Turn your breath into sound and play a deep rooted Gaelic air, a pop ballad, a 2/4 pipe march, a church Hymn, a Vedic chant, a Christmas Carol, a funk riff or a soaring improvisation - it's up to you. 

The mk Pro is the original mk whistle which has since become a firm favourite with musicians around the world. It's development is an evolution which started in a workshop in Abriachan, overlooking Loch Ness in the Scottish Highlands.  

Like all great instruments, it is the mk Pro's sound which sets it apart. The chances are you are here because you saw a YouTube review or you tried a friend's mk Pro and it jumped out, but do not fear if you haven't - make use of our satisfaction guarantee and try one in the comfort of your own home wherever in the world you are.

  • Comes with a Nordic style thick real-wool felt sleeve.

Freedom, Expression, Authenticity.

Playing whistle is free from rules and constraints. Technique has not been 'formalised' like on some musical instruments and there aren't any associations or governing bodies deciding how things should be done 'properly'. This is perhaps why in many places it is one of the strongest bearers of authentic local culture. 

A Labour of Love

For several decades we have been pioneering the craft & design processes involved in making whistles. It's a gradual and at times painstaking process, making improvements, sometimes absolutely tiny, to bring you the best possible instrument to make music with - so you can enjoy one of the great things in life. And this is the beauty of making instruments - a whistle itself is like any ordinary object, until it is in your hands. It is a collaboration, a symbiosis, between maker and musician, and an expression of life itself.  

Health & Happiness

In today’s modern world, maintaining our health is perhaps more important than ever. Engaging in the creation of music combines all of the things that are in scarce supply - aiding focus, discipline, interaction with people, and teaching tolerance of failure as a means to mastery. It has also been scientifically proven to reduce anxiety and increase a sense of belonging. Of course it has huge benefits for our mental health, but on a simple level, it allows us to live the kind of artful, soulful and fulfilling life we want to lead.  

Buy Once 

When learning & playing music, it's nice to see your progress and know you are playing a musical instrument that isn't holding you back. With some musical instruments you need to spend a lot of money for that high quality instrument. With whistles, we are lucky - a world-class whistle will not cost the same as a world-class violin for example, and yet they might share the same stage or film soundtrack.

Try & Buy in Confidence!  

We understand you really need to try an instrument - a great whistle has to be felt and not just heard; how does it blow, how does it respond?  And sometimes finding exactly the right one can be a journey. 

This is why we offer a trial period.  You can try an mk whistle in the comfort of your own home - your kitchen or in whichever space you are used to the acoustics, and you have 21 days, from the date you receive it, to return it. If you use an approved shipping partner we will pay return postage and refund you the whole amount if you decide to return it! So trying an mk whistle will cost you nothing. (You should probably know we don't get many back though!) And of course, every whistle is covered by a unique 10-year guarantee.

Buying musical instruments online?

It used to be that if you bought a musical instrument online you would have no opportunity to try it, and then no opportunity to return it if you didn't like it. It was a lottery - and you couldn't be sure what you would get. But we have many happy customers all over the world, some of whom own and cherish every model and every key of mk whistle, and all of whom ordered online. We managed this by focusing on not just high quality - in terms of sound, play-ability, durability and aesthetics - but maintaining that quality consistently - something which can only be achieved by true mastery of our craft. People keep ordering and are excited to receive an mk whistle to their front door, wherever in the world they are, because they are confident what comes to them will be excellent.
