Tiento is a common form from the 16th century in keyboard music for historical organs, similar to fantasy. Tiento de falsas, Tiento of "false" (or wrong) notes, refers to the use of dissonance and chromaticisms. Like the piece Quasi-Lontano (2023), it was designed as a tribute to Ligeti's centenary (2023) using Ligeti's chromaticism and compositional methodology in an open form with an exploratory sound nature. Its instrumentation is the historic organ and Moog analog synthesizer with Moog analog delay pedal, both controlled via CV by Theremin. Expanded techniques are used, such as the feature of overlapping octaves on the split keyboard (characteristic of the Portuguese historical organ), use of weights to hold notes (on both instruments) and gradual opening of the organ's registers. The synth is programmed with an arpeggiator and extremely slow LFO that alter the height of the second oscillator and the resonance of the filter. The Theremin controls the amplitude and opening of the filter.
