Compose Epic Movie Themes on Piano Using the Andalusian Cadence (Part 7)
You can compose an epic movie theme on piano by playing the Andalusian cadence (i–bVII–bVI–V, in D minor Dm–C–Bb–A) in the left hand. Then either climb the right hand in diatonic thirds in contrary motion with a war-drum thumb rhythm, or repeat a short motif such as F E D A and vary its speed, register and dynamics.
Key points
- The Andalusian cadence in D minor is Dm – C – Bb – A (i – bVII – bVI – V).
- Idea 1: descend the bass and ascend the right hand in diatonic thirds, in contrary motion.
- Alternating thumbs create a war-drum effect while the pinky holds the pulse.
- Idea 2: a four-note motif, F E D A, with the accent on E, over root–octave bass.
- Vary register, dynamics and right-hand speed so one theme fits many scenes.
What this lesson teaches
In Part 7 of the Andalusian Cadence series, Jason Zac of Nathaniel School of Music shows two ways to turn one chord progression into cinematic, film-score style piano music. These are not finished melodies. They are composing ideas you can develop and make your own. The lesson suits pianists who already know the Andalusian cadence and want to use it creatively.
The Andalusian cadence is a falling minor progression: i – bVII – bVI – V. In D minor that is Dm – C – Bb – A. The first three chords come from the natural minor, with its flattened seventh. The final A major chord borrows the raised seventh (C#) of the harmonic minor. This mix gives the progression its floating minor feel.
Movie theme idea 1: contrary motion
Step 1: Bass down, melody up
The left hand plays the root of each chord as the progression falls: D, C, Bb, A. The right hand starts on D and climbs step by step through the D minor scale while the bass descends. When the left hand moves to C, the right hand goes up to E, not Eb, because it stays inside the scale. It keeps climbing against the falling bass.
To give it shape, let the right hand play each note twice while the left hand plays once. Add an eighth note at the end of the bar, counting and two and three and four and.
Step 2: Add thirds
To make the theme bigger, harmonise the right-hand line in diatonic thirds: D with F, E with G, and so on up the scale. The right hand climbs in thirds while the bass descends. This is contrary motion, a long-standing technique in Western classical composition.
Step 3: The war-drum effect
For a huge climactic scene, imagine a room full of giant war drums. You can suggest that sound on the keyboard by rapidly alternating your two thumbs to create a pounding drum rhythm. Meanwhile, the pinky keeps the steady pulse. Keep the contrary motion going, with the melody climbing and the bass dropping, over this rhythmic engine.
Step 4: Think polyrhythmically
Many students find the pattern easier when they hear it as a polyrhythm, with the two hands working as separate rhythmic layers that almost lock together.
Step 5: Use dynamics and register
Real dynamic control only comes once the rhythmic engine is steady. Then try the same music in different places on the keyboard: higher and softer, lower, or very low. The same material can serve many different scenes in one film, from desolate to monstrous.
Movie theme idea 2: a simple motif
Keep the same Andalusian cadence in the left hand: D, C, Bb, A. Now play root and octave, toggling between them.
The right-hand motif is just four notes: F E D A. You can place it low, around middle C, or higher. Accent the E strongly so it feels like the downbeat, beat one. If always landing on A gets monotonous, pivot the tune by changing the final note so the motif moves with the harmony.
At a slow pace the motif sounds haunting. Then double the speed of the right hand without changing the tempo. Only the right-hand rhythm gets faster, and the result feels more chaotic and urgent.
How to practise
- Play the left-hand roots D, C, Bb, A until they are automatic.
- For idea 1, add the climbing right hand, then the thirds, then the thumb drum pattern with the pinky pulse.
- For idea 2, practise the motif slowly with the accent on E, then double the right-hand speed.
- Replay each idea in different registers and dynamics, and record yourself.
What makes a movie theme
A movie theme is one idea, motif or hook that can survive the whole film. It recurs again and again at different intensities and dynamics. You can then pick and choose versions for different scenes, especially static ones where the music has to bring the life. Final choices depend on the director and the visuals.
Questions about this lesson
What is the Andalusian cadence?
It is a descending minor progression, i – bVII – bVI – V. In D minor that is Dm, C, Bb and A, and the final A major chord comes from the harmonic minor.
How do I make piano music sound like epic war drums?
Alternate your two thumbs rapidly to create a pounding drum rhythm while your pinky keeps the steady pulse. Combine this with a falling bass and a right hand climbing in thirds.
Why does the right hand play E and not Eb over the C chord?
The right-hand melody follows the D minor scale, and E natural is the scale note above D. Eb would fall outside the scale.
How can one theme work for different movie scenes?
Play the same idea in different registers, at different dynamics, or with the right hand at double speed over the same tempo. The music can then sound haunting, desolate or chaotic as the scene needs.
