Thidell Formula 1™

Anders Thidell used all the knowledge and experience he accumulated in over 15 years of study, experimentation and development to design this temperament specifically for the guitar.

If you mostly play in "guitar keys" then Thidell Formula 1 is for you. It is optimised for all the standard open and barre chord patterns. Major keys in Formula 1 which sound closer to the natural tone row are: E, F#, G, A, B, C, D. Minor keys which sound closer to the natural tone row are: E, F#, G#, A, B, Eb.

The remaining key signatures in Thidell Formula 1 all sound harmonically acceptable to the ear, with varying degrees of tonal colour. Nothing sounds dissonant, but interesting, subtle effects are created which add harmonic "spice" to the mix. This applies to all the keys to some extent, and is a valuable tool which can add to the emotional "feel" of the music. (See: Key Colours)
