This is a frequency and wavelength chart for real (and extrapolated out to beyond real) musical notes.
Notice the lower frequencies are in [decimal] feet, the middle frequencies are in BOTH feet and inches
and the highest frequencies are in inches only for convenience.
The boxes closest to 20 Hz and 20 KHz, the defined limits to human hearing, have pink backgrounds. A-440 is in a YELLOW box.
The area around 80 Hz, the suggested crossover freq for Home theater /surround systems has 2 boxes marked in a recognizable tan color. The fundamental frequency of the lowest note on a regular piano = A0 = 27.5 Hz and the highest is C8=4186 Hz.
These boxes are white on black. The Boesendorfer Model 290 has 9 extra sub-bass notes down to the low C at 16.4 Hz.
FULL WAVELENGTHS ARE SHOWN; REMEMBER A HALF WAVELENGTH IS HALF AS LONG.
Since sound travels at about 1130 ft/sec at approx 68 degrees F, a frequency of 1130 Hz would have a wavelength of a foot.
The closest box is in GREEN so it's easier to find.

NOTE: If you adjust the FONT SIZE appropriately, you will also adjust how the chart prints on paper.

The numbers shown are "fundamental" frequencies. The physical characteristic that enables your hearing to determine the difference between an "A" note played on a trumpet, a piano, a guitar, and a clarinet is due to the fact that each instrument has combinations of harmonics, both even and odd ordered. It is the ratio and the loudness envelope (attack / decay / sustain / release) of each of these harmonics, all playing in unison, which enables us to tell the difference between instruments. Only pure sine waves from a generator (or computer) are their stated numerical frequency. A "middle C" on a piano has a fundamental of 261.6 Hz, but also various combinations of both even numbered and odd numbered harmonics, typically all the way up to 16744 Hz. That's the 64th harmonic !
