See you tomorrow with another tip like this. If you get to the middle east and the far east, you get into more chromatic kinds of harmonies and they’re organizational structure of music is different than ours. One more thing, diatonic harmony is used in western music and by that, I don’t mean country western music, I mean, Europe and the Americas. If you enjoy these little tips, come on over to and sign up for tips. That’s really all you need to know about that, so that’s for being with me. They’re basically diatonic, but they get into chromatic harmony once in a while too. Okay? Now, most songs are made out of both. Diatonic means the you’re based in a given key and you’re only using the notes of that key. That’s a submediant chord, and that’s a leading tone. That’s the fourth chord called a subdominant. If I build a chord on the third degree of scale, that’s E minor, all diatonic because we’re not using any notes that aren’t in the scale. That would be a diatonic chord too but that happen to be major, that’s a D minor. Trying to find information about this technique seems to be difficult as it mostly seems delegated to Jazz making it somewhat obscure. Generally speaking it follows a progression of Bb/Bsus4, F/Fsus4, Ab/Fm, Cm/Csus4 and the notes within those chords to make it chromatic are Bb, A, Ab, G. The tonic chord of the key is C, guess what it is? Of course it’s C, isn’t it? That’s a home based court, it’s tonic. So I picked it a part and analyzed the chords. If you’re in the key of B, it’s still whole step, whole step, half step, whole step, whole step, whole step, half step. In diatonic harmony, we have eight keys, eight notes, but they’re always arranged like this, whole step, whole step, half step, whole step, whole step, whole step, half step, no matter what key you’re in. It’s not diatonic anymore because it goes out of the key. For example, if I’m in B flat and I want to play (plays piano) that note, that’s an augmented chord, but it’s also a chromatic harmony. The contrast to that is chromatic harmony where you use some notes that aren’t in the scale. If I play chords made out of just those scale notes, that’s a diatonic. For example, if you’re playing in a key of B flat so (plays piano) that’s a diatonic scale. Tonic of course means the tonal center of a key you’re playing in. That word, diatonic, and it puzzle some people, it’s actually made out of two parts dia, D-I-A like diagonal, means across or through. Today, we’re going to take a look at diatonic harmony and chromatic harmony. You don’t always use all these things, but it’s good to know what other musicians are doing as well. We’re focusing on music theory, some things that every piano player and every musician needs to know. Again, this is Duane and we’re doing a series called Good Stuff You Really Ought to Know About Music. D chromatic scale No.Most Songs Are a Combination of Diatonic Harmony And Chromatic Harmony The final 13th note is the octave note, having the same name as the starting note. In this case, the first explanation above applies - we will continue to use sharp notes ascending and descending to match the scale. An example D chromatic scaleįor this example - the chromatic scale in the key of D, let's assume that we are working with a key that is on the circle of 5ths - D major scale, which is a sharp-based key signature, and we want to identify some chromatic scale notes outside that key. when playing the notes from lowest to the highest pitch, then use flats when descending. Chromatic scales without a key signatureįor both C major key signature and A natural minor key signature, there are no sharp or flat notes, so since there is no key signature, we have no clue as to whether to use sharp or flat names to identify any non-natural notes.Īlthough there seem to be no generally agreed rules on how to handle this, one common music theory convention is to use sharps when ascending the scale ie. Eb major key signature, where flat note names would be used. The same principle applies to flat-based key signatures, eg. G major key signature, and we want to use the chromatic scale to identify notes outside that scale, sharps would be used for those chromatic scale notes. major scale, or any minor scale), then the key signature will be the guide as to whether to use sharps or flats for the chromatic scale.įor example, if a sharp-based key signature is used, eg. If chromatic scale notes are being used and identified within the context of a scale with a key signature (eg. Chromatic scale naming in the context of a key signature When it comes to naming the notes shown in the last step, the decision to be made is whether to use sharp or flat note names, both ascending or descending. This step gives note names to the piano keys identified in the previous step.
