This is a list of the fundamental frequencies in hertz (cycles per second) of the keys of a modern 88-key standard or 108-key extended piano in twelve-tone equal temperament, with the 49th key, the fifth A (called A 4), tuned to 440 Hz (referred to as A440). [1] [2] Every octave is made of twelve steps called semitones.

10 Seconds is a television game show that aired on The Nashville Network from March 29 to September 24, 1993. After the last episode aired, the show went into reruns until March 25, 1994. The show was hosted by Dan Miller and announced by Don Dashiell.
The couple with the most seconds of time at the end won the game. If the game ended in a tie, a toss-up tiebreaker question was asked and the first player to buzz-in with the correct answer scored one additional second and won the game. The winning couple won a chance to play the final round.
In music, the fundamental is the musical pitch of a note that is perceived as the lowest partial present. In terms of a superposition of sinusoids, the fundamental frequency is the lowest frequency sinusoidal in the sum of harmonically related frequencies, or the frequency of the difference between adjacent frequencies.
Frequency (Hz) Octave Description 16 to 32 1st The lower human threshold of hearing, and the lowest pedal notes of a pipe organ. 32 to 512 2nd to 5th Rhythm frequencies, where the lower and upper bass notes lie. 512 to 2,048 6th to 7th Defines human speech intelligibility, gives a horn-like or tinny quality to sound. 2,048 to 8,192 8th to 9th
A slight adjustment can alter it to 100 Hz, exactly one octave above the alternating current frequency in Europe and most countries in Africa and Asia, 50 Hz. In most countries of the Americas—where the AC frequency is 60 Hz—altering A# on the fifth string, first fret from 116.54 Hz to 120 Hz produces a similar effect.
The team must attempt to uncover the nine notes of the final tune over the course of 30 seconds, by using a buzzer to stop a random flashing light in order to choose a note, and then picking the correct next word, as in the first three rounds. However, the final tune is only played once, at the end of the 30 seconds.
