"Keywords," the title of this two-part concept album, cleverly plays with the English word "key," which carries a dual meaning, referring to both the piano key and the key itself. With one exception, the album features pivotal words from piano music of the 20th and 21st centuries, curated in a highly personal selection, including some premier recordings. The intention is to delve into a fundamental question of musical interpretation and composition: "how to address people with music." This doesn't imply the notion of making music verbally communicate. Instead, the pieces themselves are "speaking" works – piano compositions containing explicit or hidden messages, referencing poetry, incorporating language, words, or syllables, engaging in dialogues, resembling diary entries, or narrating entire stories. Moreover, the piano itself takes on various "voices" – whispering, stuttering, calling, hesitating.
