Compose a 30-second soundscape dominated by loud and varied cow mooing. The central sound event will be the clear, rhythmic squish and squelch of hand-milking a cow. The mooing should begin with the clink or thud of a bucket being placed under the udder and persist throughout, with natural changes in pitch and intensity. The hand-milking sounds should be consistent and distinct, creating an immersive auditory scene of vocal cows being milked by hand.
