All courses and seminars are grounded on the principle that the tuning of any instrument as well as the intonation of the voice are fundamental to the creation of a resonating and harmonious ensemble. Today we can share a new approach to the musical scale and combine simple and complex chords in a fully harmonious dimension.

The Equal Temperament, developed three centuries ago, is sometimes described as a "compromise", or in other words as a solution which is in some way limited or approximate. The Chas Harmonic Temperament, in contrast, describes a perfect whole, a precise geometry of sound which exactly recreates the logarithmic order we find in nature; today this can be part of our experience when we play a musical instrument.

Any musician or composer who is interested in learning more about both the theoretical and the practical aspects of this complex question (the subject of a vast amount of research over the centuries) will find themselves enriched by a greater understanding of melody and a deeper, more accurate perception of the hierarchy of chords.

The benefits are perhaps different, but just as great, for professional tuners and for musicians who tune their own instruments. Today they are still taught to expand the first octave by copying the first 12 notes, without any other more precise guidelines. Now the Harmonic Temperament provides two scale constants: two intervals which span more than an octave and which, note after note, can guide us towards the achievement of the right sound. Chas also defines the chromatic curves for simple intervals like fourths, fifths and octaves, throughout the whole scale, so that the piano and all the instruments of an orchestra correspond perfectly to each other in pitch, independently of each instrument’s range.

It is my wish to be able to continue to share the Chas Harmonic Temperament with an ever-growing number of piano technicians and musicians.
