Do modulations from a major key to a mode count as ‘key changes?’?



Asked by: Brian Zhou

For instance, a modulation from D major to B minor wouldn’t have a key signature change. They’re just words, honestly.

What constitutes a key change?





An abrupt key change is a device sometimes found in popular song, in which a verse might be repeated but with melody and harmony all moved up a step. The key changes, but it’s not really a modulation. Think of this as being like rectangles and squares: not all rectangles are squares, but every square is a rectangle.

How do you modulate a key change?

The smoothest way to modulate from one key to another is to use a pivot chord. A pivot chord is a chord that both keys share in common. For example C major and G major share four chords in common: C, Em, G, and Am. Any one of these chords can be used to transition smoothly from C major to G major.

Can you modulate between modes?

The use of the modal modulation technique allows you to play with how each mode makes you feel in the form of a chord. In the middle of a chord progression, as borrowed chords; or in a new section of your music, for contrast; it will take your harmonies to a different level. So, moving on!

Are keys the same as modes?

Think of it this way: A KEY refers to a particular “home base” or tonic note. For example the “Key of C”. But that doesn’t tell you anything about the rest of the notes that will be used. A MODE refers to a particular set of half steps and whole steps, but does not specify any one tone.

Does modulate mean key change?





Modulation = Key Change



When we are talking about a song, modulation means to change key. This can come into play in a variety of scenarios. First, let’s say you are playing in a band, rehearsing a Led Zeppelin song.

How can you tell if a key has changed in a song?

In general there are a couple of beats where chords are shared between the two keys. You can think of these chords as belonging to both keys and establishing the transition. Once you hit a new chord or tone that does not belong to the first key, at this point you are definitely in the new key.

What can a major modulate to?

It builds energy and it's a staple of pop and rock music but a jazz song requires something a little more subtle. And that's where the second technique comes in this is called a pivot modulation. And

Why do key changes sound good?

Relaxation in energy would be the opposite direction, usually. Large changes in key signature (many accidentals changing) are more likely to give a sense that you’ve gone somewhere pretty far from where you were, and small changes seem nearer by.

How do you calculate key modulation?

Look for the following cues when examining music containing modulations:



  1. Look for recurring accidentals, then add them to the key signature to determine the new key. …
  2. If accidentals are canceled out, they indicate tonicizations or chromatic non-chord tones.


Are modes and scales the same?

A scale is an ordered sequence of notes with a start and end. A mode is a permutation upon a scale that is repeatable at the octave, such that the start and end points are shifted. For example, the major scale is repeatable at the octave.

Are modes chords?

For instance, you can play low E on every four beats, and then play around with the notes of an E mode, such as E Mixolydian. For a broader application, you can play a vamp. A modal vamp will return to the tonic chord often.

Mode Characteristic Pitch
Phrygian Mode ♭2
Lydian Mode Augmented 4th
Mixolydian Mode ♭7

How many major keys are there?

Since there are 12 major scales, there are 12 major keys. Likewise, there are 12 minor scales and, therefore, 12 minor keys. So there are 24 keys all together. Three of the major keys can be named 2 different ways – one way with sharp note names, and the other way with flat note names.

Are there really 30 keys in music?

If you count keys while you keep adding sharps or flats, until all seven natural notes (A to G) have a sharp or a flat symbol in the key signature, you end up with 30 keys.

Do minor keys exist?

There are a total of 12 minor keys, and each minor key contains seven notes that can be used to write music in that key. So, what makes a minor key a minor key? It’s the pitch difference between the notes in the key.

How many musical scales exist?

So how many major scales are there and why? In total, there are 12 major scales because the major scale pattern can begin on any of the 12 notes of the musical alphabet.



What scales should a pianist know?

Most piano teachers require their students to learn the 12 major scales in the following order:

  • C-Major.
  • G-Major.
  • D-Major.
  • A-Major.
  • E-Major.
  • B-Major.
  • F-Major.
  • F-Sharp/G-Flat Major.

Who invented music scales?

The use of regular measures (bars) became commonplace by the end of the 17th century. The founder of what is now considered the standard music staff was Guido d’Arezzo, an Italian Benedictine monk who lived from about 991 until after 1033.
