Hi, I was talking within a group and someone commented on the importance of adding harmonic changes within a song. I didn't have a chance to follow up. What are they?
Thanks,
Dave
 
You're Dave and you have not encountered harmonic changes ? :eek:Fie for shame ! :D
 
Probably referring to harmonies in the chord progression.

playing different harmonic notes against the chord throughout the song...

its music theory stuff - if that is the harmonic changes they are talking about :)

I can elaborate some if you like.
 
The Wetter, the better !

Seriously though, I've spent ages trawling the net and I haven't been able to find a definition ! There are videos, pdfs, articles, book sections, some of which use the phrase "harmonic changes". But all the authors must assume that the reader knows what it means because no one thinks to define exactly what it is.
So I'm going to guess and say that I guess it's where harmonies in a musical piece change ! I suspect though, that a key change or chord change will not necesarilly bring about a harmonic change but I don't know why.
 
Some of that is the context of the comment. My trombone has overtones / harmonics that sound in addition to the perceived note. These can interact with other things and even itself. It's why an F above middle C sounds different when played in 1st, sharp 4th, or 6th. Even though it's technically the same note or pitch. But in your case it's probably chord related. II, V, I and variants. Which you can alternate using II or IV for that one, V or VII for that one, and other close enough, but different things. If you're just going to play the same note(s) the same way everytime you might as well be playing to a CD or a MIDI track. Or just play the CD and stay home in some cases.
 
I've just found this;

“HARMONIC INTERVAL”: JUST A FANCY NAME FOR “CHORD CHANGE” OR “CHORD PROGRESSION”



The term interval has a considerably different meaning in harmony, compared with melody. Simply put, a harmonic interval is a chord change.


A succession of melodic intervals is represented like this:


1 – 4 – 2 – 5 – 1


Each symbol represents a single note, called a scale degree. Each dash represents a pitch change from one single note to another single note.


So far, such pitch changes have been referred to as “intervals.” From now on, they’re melodic intervals, so as to distinguish them from harmonic intervals (chord changes). So, in the above example, there are five notes and four melodic intervals.


A succession of harmonic intervals (chord changes) is represented like this:


I – VIm – IIm – V7 – I


Each symbol represents a harmonic degree, commonly known as a chord. Each dash represents a harmonic change, from one chord to another chord.


Such harmonic changes are called harmonic intervals, or chord changes, or chord progressions. All of these terms mean the same thing. In the above example, there are five chords and four chord changes or harmonic intervals.

There you go.
And there I go !

I may have encountered harmonic changes, but did not know enough to recognize them. Evidently. Thanks for everyone's thoughtful comments, yet I still don't feel like I know the answer. Are you all supposing it's just having additional chord progressions? That's what I seem to be hearing.
 
Well, until a few hours ago, I wouldn't have known a harmonic change if Bill Clinton blew 7 on his saxophone.
 
I think Grim's got it sorted... I think the someone you were talking to was
a/ being pretentious
b/ didn't know sh1t
 
Kind of like the guy who asked me why I didn't use alternate (guitar) tunings. (I have used drop D). He's a bass player, what's he know about using non-standard chord fingering?!
