I kindly request you to compose a purely piano-based piece of music that encompasses a calm and soothing atmosphere, emphasizing a slower and more laid-back tempo. The music should sound gentle, balanced, and incorporate subtle ambient sound effects to enhance the overall ambiance. It is important to focus on the piano as the main instrument, utilizing repetitive and looping rhythms while consciously avoiding overly prominent melodies or sudden loud key strikes that may disrupt the serene ambiance. This composition is intended to serve as soothing background music, specifically tailored for work and study purposes.
