• Ask Jermaine: “Transposition and Modulation”

    in Piano,Theory,Transposing Keys

    Every other Monday night, we hold a live “Question & Answer” session in our Gospel Music Training Center and last night we got a great question from Miriam Tierno in NY: “What is the difference between Transposition and Modulation?”

    So I’m going to repeat my answer concerning transposition and modulation here on the blog for everyone to see.

    The Difference Between Transposition and Modulation

    When it comes to transposition and modulation, they are very similar… yet different.

    Transposition (or the commonly known verb, “transposing“) is the act of learning a song or chord progression in a new key. For example, if a song is in the key of C but you want to play it in the key of Eb, you’d have to “transpose” it to the key of Eb using one of the strategies below.

    It’s useful in church when a singer wants you to take the original key of a song down a few half steps… or if you’re playing an instrument that is tuned differently so you may have to adjust by transposing up or down. Or perhaps, you’re a 12’er (my own term) and find pride in learning everything you know in all 12 keys — transposition is helpful for you too.

    Here are a few links to past posts that’ll show you how to transpose:

    Transposition and Modulation Continued

    Modulating, on the other hands, is the process of moving to another key while playing. While transposition is literally taking what you know in one key to another, modulation is like the actual act of going there.

    So if you’re in the key of C and you want to take the song up to the key of Db, you can get to the new key by modulating there, on the spot.

    There are many ways to modulate to a new key. The most common is to simply play the “5-chord” of the new key.

    So you’d act like you’re about to end your progression in the current key (by typically using a 2-5-1 progression) but instead of coming back to the 1, you’d go from the 5-chord of the current key to the 5-chord of the new key, which provides resolution to the new 1-chord.

    Let me give you an example:

    Say, we’re at the end of a verse in the key of C. A typical 2-5-1 progression would be:

    Dminor9 – D on left /// F A C E

    G9sus – G on left /// F A C

    Cmaj – C on left /// E G C

    When we’re ready to modulate, instead of coming home to the C chord displayed above, you’d take the G9sus (which is the 5-chord in the key of C) and simply take it up a half step, giving you Ab9sus. This is now the 5-chord in Db major and will bring you beautifully home to Db major just like the G9sus brought you home to the C major.

    G9sus – G on left /// F A C

    Absus – Ab on left /// Gb Bb Db

    Dbmaj – Db on left /// F Ab Db

    The process we just took to move from C to Db is called a modulation.

    Transposition and Modulation Review

    So again, transposition is basically saying: “I live in California and now I want to live in Florida” (thus studying where you want to live in Florida, where everything is, how to get around, etc.) Modulation is the actual road trip you take to get from California to Florida.

    I hope this helps to clarify transposition and modulation.

    Hey Jermaine,
    Cool post, that’s a good distinction to know. I get asked more about transposition than modulation since saxophones have to transpose any piano or ‘concert pitch’ music.

    Another analogy might be that transposition would be having an Italian movie overdubbed in English (for the entire movie) and modulation would be a movie in English that has a scene where all the actors speak Italian since they’re on a short trip and then in the next scene they go back to speaking English.

    Great analogy Neal. Always good to hear from you.

    To add, sometimes a song will modulate to a new key and end there so it’s not always a matter of going there and coming back (especially in gospel, you’ll find songs start in, for example, C major and modulate to Db… then D… then Eb… and even higher if it’s a dynamic song, finally ending in the last key).

    All the best,
    JG

    Hey Jermaine !
    You are doing such a wonderful job with music, you remind me of a supermarket in Canada where you were allowed to eat any thing FREE (but don’t take it out) if we stay focus we can reach pretty far musically, great idea ! !
    I was looking at the transposing and naming of the new notes, not that crucial, but since the sharp ( # ) raises a note and the flat ( b ) lowers, so when we are transposing (raising) the G9sus, couldn’t we use the sharp (#) so instead of
    Absus – Gb + Ab + Db it would read G#sus – F# + A# + C#
    In order to keep a principle, as I said its not a “biggy” just the flow.

    Delroy, thanks for your kind words. In the case of sus, you aren’t really “sharping” the 3. You’re replacing it.

    It’s correct to say Absus – Ab Db Eb or Absus7 – Ab Db Eb Gb

    You don’t want to be in the major scale of G#. It has 8 sharps, including double sharps. You want to be in Ab, lol, trust me.

    thanks a lot. This is an eye opener to the confusion cause by the two words.
    Pls if i understand what this article means, then i can say modulation is the process of moving from one key to another, while transposition is playing the same chord progression on the new key!
