Developing idea

A developing idea, defined in richards-2016 (par.45), is a term used to describe an idea that is not a basic idea but is also not a contrasting idea – it is in between. That is, it’s not the same, but it’s not totally different either.

As an amateur composer, the line is very blurry and what is said to be a “drastic change” does not immediately stand out as such to me.

Examples

ET: Main Theme

In this case, A2 changes its harmonic rhythm to 1 chord per measure which is supposedly a drastic change.

The Right Stuff: Main Theme

  • End of A2 melody is nearly the same as the end of A melody
  • Harmony of both A, A2 is the same
  • Beginning melodic portion of A and A2 are different

Who’s Afraid of Virginia Woolf? Main Theme

  • m2 of A2 is very different than A
  • Harmony of A + A2 follows a standard I IIm V I which connects them

Star Wars: Main Theme

  • This uses the hinge technique that is common in many of John Williams’ works
    • 2nd half of A is the 1st half of A2

The Mission: Gabriel’s Oboe

  • This one is much more loose
  • The similarity lays within m2 and m3-m5
    • m2 has a run that starts on D and ends up on A, all within m2
    • m3 begins a run that pickups on A and goes up to D, then does a much more embellished movement down towards A, finally reaching A in m5
