Maqiano™ Microtuning System for Acoustic Piano – Detailed Info

Microtuning Your Piano

The idea of Maqiano is similar to the capo / capotasto used with guitar, it shortens the “speaking length” of the string, making the tuning level go up. So it always tunes the desired pitch up, never down.

You need one Maqiano unit for every pitch (choir of strings) you want to tune. For example, if you need a B-half-flat, you just tune the B-flat up a 1/4-step. If you need microtones in several octaves, you have to tune all the B-flats separately. Once installed, you can easily fine-tune the note to any desired tuning level, usually up to a half-step up from the original pitch. You understand now, that when you tune a note up, for example a B-flat to a B-half-flat, you don’t have the B-flat in that octave anymore. If you need to play a B-flat, you have to change the octave, or remove the Maqiano unit.

The Maqiano operating range is 3 to 4 octaves, depending on your piano. In Steinway models B, C and D the range is from the lowest B-flat up to the B-flat above the middle C. About the same range in the Fazioli 212. In general, it works fine from the low range with 2 strings per pitch, to mid-range as long as there’s enough space between the strings, the tuning pins/agraffes/v-bar and the dampers/hammers. On the lowest range, with just one string per pitch, it may work fine, but may require slightly more adjusting.

The sound as well as the ease of use, is at its best on plain wire strings. The copper-wound strings are slightly less convenient, especially on upright pianos. The sound is also thinner and is more likely to buzz or crack on heavily accented notes.

The Sound of the Maqiano-Tuned Piano

With the Maqiano prototype that I used on my solo album, the timbre of the microtuned notes is quite different from the other notes. I used some other modifications to soften that difference. 

The new version is much better, but still the timbre changes a bit. This depends on the piano, range, dynamic level etc. Download the music here and listen to the difference in this new home recording without any other modifications (all C’s and F’s are tuned about ¼ step up). 
Also, please note that the best dynamic range is from piano pianissimo to forte, depending on the range and the piano model. Heavy fortissimo accents are likely to cause distortion, a buzz or a crack in the sound, especially on the low copper-wound strings, and also a bit in the highest register. Download here and listen to this sound example and then you can decide for yourself if this is a pro or a con.

Installing Maqiano

Installing one Maqiano unit takes only a few seconds. With practice, I am able to do it in 4 or 5 seconds, sometimes having to adjust it a bit after starting to play. Removing it is faster. Tuning 2 notes per octave for example, in the possible Maqiano operating range of your piano takes less than a minute. It should be possible in concert during the oud intro. Fine-tuning is very fast when you want to adjust the microtuned note a tiny bit up or down. It takes just a second or two. The previously mentioned times are for grand pianos. Some uprights are easy as well, but some smaller ones are trickier. They might take more time to tune, especially in the lower register. 

You can tune as many pitches as you want, but placing Maqiano on two adjacent choirs of strings (e.g. D and E-flat) can be difficult due to tight spaces. 

It’s a bit awkward installing Maqiano with your grand piano’s music stand in place. However, if you need to read music, you can re-install the music stand after installing and adjusting the Maqiano units. There will be enough space to do just that with most of the pianos. The same thing with upright pianos – it might be possible to install Maqiano with the front lid in place, but it can be challenging. With most pianos you can re-install the front cover after installing and adjusting Maqiano. Note that this does take some time.

The construction of Maqiano is modular. You can add and remove different parts according to your piano model and register. Maqiano is sold in sets of 4 or 6 units, so you can microtune 4 or 6 pitches. If you need more, you can order multiple sets with a discount. 

Maqiano in Concert

The system is carried in a stylish Alcantara case which also works as a stand for the Maqiano units and accessories. You just place it on the grand piano’s tuning pins, or on another horizontal level or on a chair or table next to your piano. It is best to always try Maqiano in different configurations in the soundcheck, so installing it will be faster during your concert performance.

Flying with Maqiano

I have had a few Maqiano units in my cabin luggage on roughly twenty flights now with no problems. However, the long metal bar for upright piano use, ”The Bar,” is clearly against the rules for cabin baggage and the airport security will not likely allow it. They may not let you take the Maqiano tuning units inside the cabin either due to the metal pieces being more than 6 cm long. I recommend checking in the whole system with your luggage. The Maqiano system is quite heavy; the set of 4 units weighs almost 3.7 kg. Another good reason to check it in.

Maqiano is Safe for Your Piano

I have used Maqiano quite a bit on my own Steinway, and on at least 100 different pianos around the world. No damage has ever been caused to any piano or their strings. No piano has ever gone out of tune. After removing Maqiano, the pianos have returned to their original tuning, every single time. 

No damage to your piano or the strings from using Maqiano. I guarantee it!* 

*You must read and understand the instructions, watch the instructional videos and use Maqiano accordingly, only for the purpose described.

Piano Tuner’s Statement

“I have become familiar with Kari Ikonen’s invention, the microtuning device Maqiano™, and I am assured that when used properly for its intended use, it causes no harm to the piano, its strings or its tuning.

I have been providing service and tuning for Kari’s Steinway & Sons grand piano since 2003, and I haven’t noticed any damage or changes in the piano or its strings during the last 2-year period with extensive use of the Maqiano.”

Treat Maqiano as a Precision Instrument 

Since Maqiano has strong magnets and heavy metal parts, you have to read, understand, and follow all the instructions and watch all tutorial videos that I’ll be sending along with your order. Because your piano and Maqiano are both precision instruments, you need to be careful when using Maqiano.
