Key Rhythm. Grandmother bought this used upright Larffague piano in 1917 on time for $40 (I have her payment book). HDR merge of +to-3 photos in PS. Masked to give a black background relief. LR to B&W. Liquify twirl filter to give an undulation rhythm effect. NikonD3400, ISO100 f25, 2.0s, 18mm-55mm lens @ 34mm.
