If playing piano happens to be one of your leisure pursuit, then this coffee table is sure to grab your attention. Designed by Mike Kann, “Piano Coffee table” borrows its design from waves of piano. Moving towards the wave theory, the table steals the look of the sine wave of middle A on a piano that runs the frequency of 440 Hz. The tone and timbre of the instrument represents the subtleties that crates middle A sound on piano. The glass table top cuts through the wave form to create a surface, depicting the base line that we generally find on oscilloscope readings. What an amazing design it is, I would love to play it.
