Again, no, the meaning of 'dissonance' is_not tied to 'chord'. It means a note does not 'concord' with another note. Some definitions of what is dissonant have changed, such as fourths were more liable to be called dissonant at one time. EDIT: this is contextual. One can find a discussion of the I 6/4 triad, that 4 {example G C E} called dissonant even today. As there is in that style practice the expectation 6 and 4 move to 5 and 3 (C/G bass to G). This is an example of voice-leading.*tapper mike wrote:Connosance, Concord. Means the note is found in the chord or the note is used to create the chord.
Dissonance, Discord. Means the note is not in the chord. You can create a mini resolution by going from a discord to a concord. or create a slight sense of tension by moving from a concord to a discord.
Here is the proof of concept: A chord can be built from dissonances. A secondal chord *is* a chord. Should we believe that fourths are dissonant, a quartal chord *is* nonetheless a chord.
Even should we limit this to tertial construction a dissonance means there is something IN the chord that is dissonant. Minor/major 7: C Eb B. The interval of the major seventh is considered to be a dissonance. CmAdd2: the D next to the Eb is the dissonance. It is nonetheless a part of the chord. "dissonant to the chord" doesn't have any meaning now.
EG: The 'resolution' of a 'dominant seventh chord' is the resolution of the TRITONE found in it. G B F: the B F is resolved to C E.
EG: The 4-3 resolution within a chord.
Et cetera.
Chords are just not the beginning of this kind of thought in music, there was harmony long before chordal naming became the way to go.
(*: those figures, cf. figured bass, predate the fixing of chords, the thought comes from counterpoint and eventually chord thinking is the convention)
