wave to the crowd

here is a basketball/and there a violin

one an air-inflated near-sphere/one a wood and string arrangement

both wave

the basketball goes unspherical when bounced against hardwood/and makes a distinct sound/that has an afternoise/from the post-impactal wave form of the ball itself

the violin has an interior/designed to vibrate around a supporting post/harmoniously/when the bow is drawn across the strings

violin and basketball both wave to the crowd

and when the crowd cheers it waves back
