WebJul 1, 2014 · As far as I know the tuning of a piano has to be somewhat "streched": The stiffness of a piano bass string causes the overtones to go slightly sharp. (Don't ask me why). If you hit a "wide" chord, say C-1 C-2 G-2, you might be noticing a slight beat, since the overtones of the low C are slightly sharper than the C-2 and the G-2. WebThe strings of a piano vary in thickness, and therefore in mass per length, with bass strings thicker than treble. A typical range is from 1/30 inch (0.85 mm, string size 13) for the highest treble strings to 1/3 inch (8.5 mm) for the lowest bass. These differences in string thickness follow from well-understood acoustic properties of strings.
WebPiano tuning is the act of adjusting the tension of the strings of an acoustic piano so that the musical intervals between strings are in tune.The meaning of the term 'in tune', in the context of piano tuning, is not simply a particular fixed set of pitches.Fine piano tuning requires an assessment of the vibration interaction among notes, which is different for … WebApr 5, 2024 · Piano tuning cost. Piano tuning costs $100 to $200 total or $70 to $100 per hour on average, depending on the piano's age and when it was last tuned. Piano tuners typically charge the same flat rate or hourly price for grand and upright pianos. Keeping a piano tuned may prevent costly repairs. Piano tuning takes 60 to 90 minutes on …
