Hello and welcome. In this episode, we will be looking at some practical uses for model interchange. First of all, what is it? This is a technique that consists in temporarily borrowing chords from a parallel tonality or mode that shares the same route without abandoning the established key using this technique is a great way of a of adding color and variety to chord progressions.
You can look at it as a way of working with temporary modulations that introduce chromaticism from parallel, tonalities to the tonic Center you are working on. And once we have established the tunnel or model centers that we will be using, we will know which cord and pitches are available to us and use those mind you that if any of these Concepts sound unfamiliar to you, check out the links in the description that will Thank you to the appropriate blog entry.
And with no further Ado, here is a melody in f mixolydian from the B-flat, major key Center and with borrowed cards from F aeolian, in the key center of a flat major. You can also start with a Melody that uses speeches from the keys. You choose to use for modal. Interchange automatically, you may be defining the places where the borrowed cards will be used. Here is an example, first the
melody. And then with the chords, Notice how you could already tell where the borrowed cards would come in, but remember that, as long as the borrowed chord accommodates, the melodic gesture, you don't necessarily need to change the notes in the melody. In this example, you will hear that the melody stays in the same. Key in C, Dorian, while I'm
using borrowed cards. Although the most commonly used borrowed cards, originated from the major and or minor parallel modes like C major and C minor including the respective harmonic and melodic minor as well as the symmetrical scale sharing the same root. There is no reason to limit yourself to these since the premise is that model interchange can occur with any mode that shares the same route.
For instance, it Dorian and E major Another thing to consider with borrowed chords is to use them as passage or link between two diatonic chords. In this case we will be using an A flat major chord from the parallel key of C minor as a passage between F major and G. Major chords from the C major tonality Going from one parallel mode to another may be accomplished by directly introducing. The borrowed chord in the chord progression by using common pitches.
Shared between the respective parallel modes and using Court transformation to smooth the process of modal interchange.
in some model interchange chords can be used in different ways, such as adding color by introducing chromaticism, in their Harmony and or Melody as a tool for reharmonization as pivot chords for modulation or as a link between two diatonic chords, remember that when using this technique it is important to make sure that the original key is clearly established before and after using borrowed chords Since we are working with temporary modulations, you can use the thought process in
materials involved in the model interchange approach to make definite modulations, although technically it is no longer model. Interchange per se, you are only modulating to a different key. I hope that this technique opens up other harmonic and melodic possibilities for you to explore in your music, experiment with it, and find your own ways of using this technique. It's all for now and I'll see you on the next episode. Happy composing.
