Claude Debussy is accredited with creating music which was devoid of a particular harmonic tonal center, however Schoenberg may perhaps be considered the first "atonal" composer. He wrote music in an attempt to give "equal value" to all 12 tones. He wrotePierrot Lunaire which is considered one of the first pieces completely atonal.
Atonal key refers to a musical composition or passage that lacks a clear tonal center or key signature. In atonal music, traditional harmonic structures and scales are disregarded, leading to the use of all twelve tones of the chromatic scale without establishing a hierarchy among them. This results in a sound that is often perceived as dissonant or lacking resolution, creating a unique listening experience distinct from tonal music. Atonality is commonly associated with 20th-century composers like Arnold Schoenberg.
