Our Maintenance covers
Mechanism regulation – of moving mechanical parts, keyboards and pedals
The mechanism and keyboard of each piano consist of many parts made of wood, metal or felt. Regular adjustment of the mechanism, cleaning of the inside of the piano and preparation of hammers ensure that the softness of the keyboard is maintained, as well as the quality of the operation of the entire instrument and its sound.
Lubrication of the instrument’s mechanism is necessary for the unimpeded movement of all interconnected moving parts. In addition to providing mobility, pedal lubrication also prevents unpleasant squeaking when pressed.
Intonation is a process in which we adjust the density and elasticity of the felt with which the hammers are covered. Over time, the felt hardens slightly, and the hammer also deforms slightly due to wear, which affects the sound quality. With our intonation tools, we adjust the density and elasticity of the felt on the hammers and thus ensure a beautiful sound colour and dynamic.
There is an internationally agreed reference tone called a1 (440 Hz) that is used for uniform tuning, which is a compromise to natural tuning and has become the most established form of tuning throughout history. Legend has it that in ancient times, every morning at dawn, this tone was emitted by a huge pillar of Memnon near Thebes in Egypt so that musicians could tune their instruments after it. It is said that the pillar had stopped emitting the sound at the beginning of CE. Nowadays, however, this tone is emitted by the musical forks commonly used by tuners. There are about 220 strings in a piano and a technician has to adjust the tension of each one. They are tuned in certain proportions that need to be refined. It is also necessary to remove the Pythagorean comma — a less than 1.4% error that occurs at the octave interval if we make a chromatic scale by advancing up the fifths and then descending by octaves to the area of the initial octave. The error is therefore not large, but it can be severely disturbing when tones amplify each other.
Expert in tuning and technology of pianos and pianinos. Andrej Novak trained as a piano technician in the field of modern and Viennese piano at the workshop of Bernhard Balas, and in the special field of historical piano at the workshop of Gert Hecher in Vienna. He is the owner of the largest collection of historical musical instruments with keys in Slovenia.
Sandi De Simone
Expert in tuning and technology of pianos and pianinos. Sandi De Simone graduated from the Trieste Conservatory with a degree in piano. In 1986, he completed a tuning course at the PETROF factory in the Czech Republic.
Expert in tuning and technology of pianos and pianinos. Tomaž worked as a teacher of various instruments (double bass, guitar, accordion) at a music school, and he is also an active member of quite a few ensembles. He started tuning and servicing instruments 45 years ago, during which time he gained invaluable experience in the field of piano technology.
Martin has been actively involved in music since childhood. He studied at the Giuseppe Tartini Conservatory in Trieste with a major in cello, and also successfully completed a minor in piano studies. He is also actively involved in solo and choral singing (APZ of the University of Primorska, Capella Civica di Trieste, Aegida Chamber Choir). Currently, Martin is studying piano technology at the Conservatory of Santa Cecilia in Rome.
With experience in the field of music and singing, Martin will familiarize you with the aesthetics of sound and the colour of tone in individual instruments. He will guide you in choosing a piano based on your needs, desires and expectations.
Expert in tuning and technology of pianos and pianinos. Marko Ušeničnik graduated from the Academy of Music, majoring in sacral music. In addition to tuning and servicing pianos and pianinos, he also teaches piano, guitar and cajon. He is also the choirmaster of a mixed choir. Currently, Marko is undergoing additional training in piano technology at the Conservatory of Santa Cecilia in Rome.
