How to Modulate - Music Theory
TLDRThe video explains the musical concept of modulation, which means transitioning from one key to another. It provides tips on how to smoothly change keys within a piece of music without jarring 'bumpy' transitions. The key is using a pivot chord - a chord that belongs to both the original key and the new key. This pivot chord acts as a 'door' between keys. By moving through the pivot chord, you can seamlessly switch keys. The video analyzes an example musical passage modulating from D major to A major, identifying the pivot chord used to enable a smooth transition. It encourages further learning about chords and modulation using provided educational materials.
Takeaways
- 😀 Modulation means changing from one musical key to another.
- 😮 A pivot chord belongs to both the old key and the new key, allowing a smooth transition between them.
- 🎹 To modulate, decide the starting and target keys, then find a suitable pivot chord.
- 🎼 The pivot chord acts like a door, connecting one musical key room to the next.
- 🎵 Modulating without a pivot chord can sound bumpy, like changing gears without using the clutch.
- 🎶 Put chord numbers below the music to show what key you're in at each point.
- 👂 Listen for a smooth modulation between keys when the pivot chord plays.
- 📝 More advanced music theory details on modulation are covered elsewhere.
- 🎶 Choose an appropriate pivot chord to make modulation feel natural.
- 😀 With good pivot chord usage, modulating keys can be fun and rewarding!
Q & A
What does modulation mean in music?
-Modulation means changing from one key to another key. It is changing the tonal center of a piece of music.
Why can an abrupt modulation sound bad?
-An abrupt modulation without proper preparation can sound bumpy, like changing gears in a car without using the clutch. It needs a pivot chord to transition smoothly between keys.
What is a pivot chord?
-A pivot chord is a chord that belongs to both the original key and the new key you are modulating to. It connects the two keys and allows a smooth transition.
How do you find potential pivot chords?
-Analyze the chords from both keys and look for chords that are common between them. Those can potentially serve as pivot chords for modulation.
Why must the pivot chord have notes that are in both keys?
-The pivot chord must have notes that are in both the original key and the new key so that it "belongs" to both keys harmonically. This allows a smooth change between keys.
What should you do before and after the pivot chord?
-Before the pivot chord, you are still in the original key. After the pivot chord, you are in the new key that you have modulated to.
How does the pivot chord work?
-The pivot chord works like a door between rooms. It connects the old key and the new key, allowing you to pass between them smoothly through the "door".
What if you modulate without a pivot chord?
-Modulating without a pivot chord will likely sound very abrupt and "bumpy". The change to the new key needs to be prepared with a pivot chord.
What are the steps to modulate smoothly?
-Decide starting key, choose target key, analyze potential pivot chords, select your pivot chord, compose in original key up to the pivot, then continue in the new key after.

Outlines
🎵 What is modulation in music and how to change keys smoothly using a pivot chord
Paragraph 1 explains what modulation means in music - it refers to changing keys from one key to another. It notes that some composers have trouble with modulation because there can be a bumpy, jarring change when suddenly going to a new key. The paragraph explains the concept of a pivot chord, which is a chord that belongs to both the old key and the new key. Using a pivot chord allows for a smooth musical transition between keys, like changing gears smoothly while driving. An example 8-bar melody is analyzed, showing how a D (I) chord acts as the pivot chord for a modulation from D major to A major.
🚪 The pivot chord connects the old and new keys like a door between rooms
Paragraph 2 further expands on the pivot chord analogy, comparing it to a door between rooms. Just as you can't simply walk through a wall to get to another room, you can't abruptly switch musical keys without it sounding bumpy. The pivot chord provides a doorway between keys to allow a smooth transition, belonging to both the original key and destination key. An audio example is played, demonstrating how using the pivot chord results in a smooth key change from D major to A major.
