Truck Driver's Gear Shift, also called pump-up modulation, is a trick where the key of the song is lifted by 2-3 semitones, giving it a brighter vibe. In movies this usually happens towards the end, after all the variations are done, to land on a higher note. Think of songs like "My Heart Will Go On" from Titanic or Whitney Houston's "I Will Always Love You".
In film scores, the same idea is used to boost the adrenaline rush or hint that something epic is about to happen - like in Star Wars: A New Hope by John Williams, Raider's March, or Test Drive by John Powell.
In this particular score, the dark synths in the background and the main vocal "THIRAAREYYY" set up a war-like atmosphere. Then, when Lord Rama takes centre stage, MM Keeravaani slams the clutch and shifts the gears up by 3 semitones (from C# to E) with a massive choir, making it feel divine. Usually it's done smoothly, but MMK just bursts through the door, and it works perfectly here.
Maybe this sounds unpopular, but Rajamouli wouldn't be anything without his dad and brother.
The Baahubali OST is my elixir of life.
Edit: Alright, not going too far, guys - SSR is my favourite filmmaker, I respect his craft. I should've phrased my statement better.
Got goosebumps.
Can't wait to watch this one.
In Rajamouli we trust.
I get chills every time this part of the trailer plays in the theatre.
What a lovely breakdown of the musical symphony.
MM Kreem sir was hugely underrated for a while even though he consistently delivered good melodies. It's only thanks to a director like Rajamouli sir, who recognised his full potential and gave him the sky to shine.
