Middle C is 261.63 Hz. The next half-step up (C#) is 277.183 Hz.

Why are these notes, while a tone at, say, 265 Hz, is not? Or what about 269.1488 Hz -- nearly absolute middle of the two?

Why do we recognize certain frequencies as notes?

The music scale you're referring to is only the Chromatic scale. There are tones between the half steps (quarter steps) between the quarters (1/8ths) and possibly between the eighths as well.

There are several musical scales that can reach these tones and & frequencies - Ionian, Dorian, Phrygian, Lydian, Mixolydian, Aeolian, Locrian, Major Pentatonic, Minor Pentatonic, Arabian, Egyptian, Hawaii, and Japanese scales like Ryukyu and Miyakobushi are all I know off the top of my head.

Look em up.

  • Ionian, Dorian, Phrygian, Lydian, Mixolydian, Aeolian, Locrian,

Those are modes, not scale. Formed by changing which note you start with in a musical scale.

Modes are still scales.

Maybe colloquially, but 'scale' is being used meaning several things at once here. They are built on the diatonic scale, which is a subset of the chromatic scale. To offer dorian or ionian as an alternative to the chromatic scale is nonsense.

Worse, none of this has to do with pitch. You can say A=420 and build a chromatic scale using it.

This isn't what op was asking.

Get a fretless instrument and there's infinite tones.

You can pick whatever freq you want for any note you want. Every octave is double that.

The notes we use are just a standard we've set.

If anything, he's hinting at the difference between equal temperament vs just temperaments.

Incorrect, yet strangely the most popular answer here.

These are MODES - just different ways of arranging the tones.

There are [possibly] ... tones between the eighths as well

Of course there are. Harmonics aren't discrete; you can pick any frequency to arbitrary precision and it has an associated tone.

OP, ignore this guy

You have no idea what you're talking about. The chromatic scale IS NOT THE UNIVERSAL SALE USED AROUND THE WORLD - it was decided that it would be THE PRIMARY SCALE FOR WESTERN CULTURES AND MUSIC.

Listen to traditional Japanese music compared to European and American classical - the tones are completely because they use different instruments to achieve their sounds.

OP IGNORE THIS GUY

LOL

You are refuting things that I never said or implied. Of course 12 TET isn't the only way to divide the octave, but you act like there isn't a tone corresponding to every frequency out there. The problem isn't so much that what you think you know is wrong, you are just explaining it in a way that is completely off base.

You know something, but you don't know the difference between scales and modes, or between scales and tones.

To say that the (e.g.) Dorian mode (say, of F) can "reach" frequencies that the regular Eb major scale can't "reach" is ludicrous. They're the same [set of] notes.

At this point I would adjust my original warning:

OP, don't ignore this guy, but rather use him as an example of how a little knowledge in the wrong hands can be destructive.
