Question: I refer to this question (which is protected, but I cannot answer because it is 'protected') [What are the differences between tone, note, and pitch?](https://music.stackexchange.com/questions/3262/what-are-the-differences-between-tone-note-and-pitch).

In it, Matthew Read accepts Kos' comment "I believe that note is more than a "named pitch", because it also carries information about the temporal length... Doesn't it? – Kos" and agrees that "note" is a named pitch with temporal information. Thus, 'tone' could be defined as (named/unnamed) note with information about timbre. A sound produced electronically consisting of a note on a single pitch could be a tone - perhaps a 'pure' tone, one without overtones. All other methods of producing sound have overtones so calling them whole tone or semitone on any instrument is correct.

Answer: 
'Tone' is a word with at least 3 distinct meanings:

* **a synonym for' timbre'**
* **a note or sound - often an electronically-produced one.**
* **an interval of a certain size (i.e. two semitones!)**
* ...and probably more....

No, that isn't commonly-understood as a precise, *single* definition. It sounds like a blurring-together of the first two meanings above.

No. As you referenced, *note* means a tone or pitch **with temporal information.**, as in *half-**note***, *quarter-**note*** etc.

*Tone* has no connection to temporal information, as is clear from @topomorto 's definition. 

*Note* should not be connected to timbre at all. Many instruments, with a very wide variety of timbres, can all play exactly the same *notes*. A violin and a clarinet, for example, might play from identical notations, although their timbres are very different.

“a note with information about timbre” is closer to *pitch* than to *tone*, which is usually understood to mean an abstract sound - an audio frequency - lacking information about timbre or time. *Pitch* is a *tone* **with** information about timbre. 

But again, *pitch*, like *tone*, has no connection to time, which is the essence of *note*: a discreet period in relative musical time.
