Back in 2015, an advance copy of Disturbed‘s “Immortalized” landed in my inbox ahead of an interview with guitarist Dan Donegan – and buried on it was a cover of “The Sound of Silence“. I instantly knew that would be a massive hit, if only because it was such a departure from what the band had done before.

When I pulled up the official score for the song, I was surprised by how little of that transformation is harmonic. The cover sits in F♯ minor, three sharps in the key signature, with a chord vocabulary that would have been entirely familiar to Paul Simon in 1964. The drama lives almost everywhere except the chords. So let’s look at what actually changed, and what didn’t.

What Stayed The Same: The Harmony of “Sound Of Silence”

Simon wrote and recorded the originalThe Sound of Silence” in 1964, playing his guitar with a capo at the sixth fret and fingering shapes for Am, G, F and C. That capo pushes the recording’s sounding pitch up to E♭ minor (you’ll also see it written enharmonically as D♯ minor). It’s worth knowing that many published lead sheets and chord sites notate the song a semitone lower, in plain D minor – or list it by its relative major, F – for readability, so you’ll see the original’s key quoted both ways depending on the source. Either way, strip the capo off and you get the same textbook modal-folk progression in A minor: i – ♭VII – ♭VI – ♭III, or Am – G – F – C.

Simon never reaches for the raised seventh that would give him a true dominant – no E or E7 pulling hard back to the tonic. The whole song lives in natural minor, the Aeolian mode, which is exactly why it never quite resolves the way your ear keeps expecting it to. It’s a song about not being heard, so having a harmony that refuses to land cleanly fits really well.

Disturbed left all of that alone, simply lifting the whole song up into F♯ minor – a minor third above the recording’s sounding key (or a major third above the D minor of the common charts; same destination either way). The cover’s progression is the same set of relationships: F♯m – E – D – A, the identical i – ♭VII – ♭VI – ♭III shape. No added dominant, no reharmonization of the bones, no clever substitutions smuggled in under the orchestration. The skeleton on the sheet music is Paul Simon’s.

What Did Disturbed Change?

Which raises the obvious question: if the harmony is the same, where does the menace come from? The answer is that Disturbed rebuilt the song, working with producer Kevin Churko, in every musical dimension except pitch content – tempo, dynamics, register, timbre, and orchestration – and that turns out to be more than enough.

Start with how it opens. Where Simon’s guitar establishes a steady, almost lulling fingerpicked pulse from the first bar, the cover begins with a single piano, spare and slow, notes left to ring into empty space. The tempo is noticeably broader than the original’s gentle folk gait. Then comes the part that makes the arrangement famous: the build. And the genius of it, structurally, is that the song lifts without ever changing key. There’s no triumphant modulation up a step to manufacture excitement – the trick a thousand power ballads reach for. Disturbed stays anchored in F♯ minor from the first bar to the last and generates the entire arc through accumulation. Each verse adds mass. Strings creep in under the piano. A low drone and bass thicken the floor. Drums arrive late and land like something structural giving way. By the final section, the distorted guitars and full orchestra are pushing against the same modest four-chord progression that opened the piece in near-silence, and the contrast between the harmonic simplicity and the sheer weight of sound is really powerful.

A key change is the easy way to escalate. Doing it purely through dynamics and orchestration – taking a progression from pianissimo solo piano to something close to orchestral fff while the chords stay put – is harder and, here, far more effective.

How David Draiman’s Cantorial Training Reshapes the Vocal

David Draiman, you know that “wha-a-a-a!” guy from “Down With The Sickness“, well, he was trained in Jewish cantorial singing before metal claimed him. He has a controlled, resonant low baritone that most of his Disturbed catalog never asks him to use. He opens the song down there, quiet and close-mic’d, deliberately holding back the snarl that fans associate with him. Over the course of the song, his line climbs, roughly two and a half octaves from bottom to top, and crucially, that climb tracks the orchestral build beneath it. By the final statements of the title phrase, he’s at full power up in his chest-belt range, that cantor’s control bending toward a roar.

That registral journey is part of the score’s drama in a way it simply isn’t in the original. Simon and Garfunkel sing the melody in close two-part harmony at a fairly consistent dynamic and tessitura throughout. Disturbed turns the melody into a single ascending line that starts as a whisper and ends as a scream, mapping the lyric’s growing desperation directly onto pitch and volume.

Put it together and you can see why the two versions feel like they’re about different things despite sharing every word and nearly every chord. Audiences and, tellingly, Paul Simon himself signed off on the result. After the band’s orchestra-backed performance on Conan in March 2016, Simon emailed Draiman to call it a powerful performance, and Draiman, by his own account, was floored. The cover reached number 42 on the Hot 100, dominated the rock charts for years, earned a Grammy nomination and a multi-platinum certification, and its video has since passed a billion views.

None of that came from rewriting Paul Simon’s song. It came from understanding it well enough to leave the notes exactly where they were and change everything else. It can be a good reminder that the chords are a starting point, not the story. What you build on top of them is where a cover either disappears or becomes its own thing.
