The vertical order of the substances was determined by observing their tenacity, that is, the length of time their aroma remains before dissipating. Those at the top are the most volatile, those at the bottom are the most tenacious. The five movements of the work correspond to these five aromatic chords.

To obtain notes and rhythms of these essential oils, I researched the chemical formula of the characteristic substances (limonene for lemon, for example).

The sense of smell works by recognizing the three-dimensional structure of the molecules; the geometric pattern of the atoms. So, with the chemical formulas, I plotted diagrams converting molecules to music, attributing the vertical axis to notes and the horizontal axis to rhythms. Finally, with these notes and these rhythms I composed the music, trying to make each movement adhere to the general impression that the aromatic chord invoked in me.

Woods: deep, Herbs: fresh, Flowers: affective, Citrus: acid, Seeds: bitter.

The title of the work comes from the combination of the words "Acoustic" and "Essence", which could be translated as: "Acoustic Essence".

Dedicated to Mayra Batalla, the love of my life.
