Getting Your Head Around the Jekyll and Hyde Duet

In His Eyes sits at measure 109 in act one of the show and is structured as a straightforward two-part duet, but that simplicity is where people trip up. The vocal range for Lucy runs from approximately F#3 up to A4 in the bridge, while Hyde's part is written in a more tenor-friendly baritone tessitura, topping out around C5 when he hits the final belts. Most sheet music editions you'll find online are adapted for voice and piano, though band versions and choral scores exist too. I've sourced this score from three different places over the years. The official Hal Leonard vocal selection book is accurate but expensive if you're buying just one song. For a standalone piano-vocal score, Musicnotes and Sheet Music Plus both carry licensed arrangements that render cleanly on screen. The Franz Harmon/ConKord versions tend to be the most performance-ready since they include the standard Broadway cut markings. Avoid any PDF that doesn't list a publisher—most of those are amateur transcriptions that fudge the harmony in the bridge section. The song opens with Hyde alone, then Lucy joins on her entrance. The key signature is D major with frequent shifts into B minor and Fminor throughout the bridge. If you're sight-reading this, the trickiest passage is the three-part interweaving around measure 47 where both voices overlap in contrary motion before resolving back into unison on "in his eyes." That section is easy to mess up if you're only looking at your own line.

The Practical Stuff Nobody Mentions

When I first rehearsed this for a community production, my tenor singer kept rushing the transition from the bridge back into the final chorus. The issue wasn't tempo—it was that the chord changes in the piano part under the verse re-entry are dense. There are several secondary dominants (V7/V, vii°7) stacked in quick succession that aren't intuitive to follow by ear alone. The workaround was having him mark the chord symbols above his staff rather than relying on harmonic memory. Specifically, the progression from measure 78 through 86 spells out Dmaj7–G#7–C#m7–F#7, which guides you back to B minor for the bridge entrance. Once he could see those alterations written out, the rushing stopped completely. Another thing that catches people off guard: the final chorus demands a dynamic swell that isn't as obvious in the score as it should be. The original cast recording has both voices rising together, but many edited sheet music versions cut the final four bars of the duet entirely because they're considered difficult to stage. If you're performing this in a recital or audition context, make sure your edition includes the complete ending. There's a version floating around from Franklin Watts Music that trims the last section down to a single held note, which completely changes the emotional arc of the number. The piano reduction in most editions does a decent job covering the orchestral string figures, but the left-hand accompaniment in the bridge has some wide jumps that can be awkward for smaller hands. I had a pianist struggle with the octaves at measure 34, so we ended up rolling the inner harmony chords instead of playing them starkly. It sounds fine in context and gives you a moment to breathe during faster rehearsal runs.

What to Check Before You Buy

Not all arrangements are created equal. Some editions transpose the Lucy part down a half step for sopranos who aren't quite comfortable in the upper register. Others keep it concert pitch but reduce the bridge range. Before purchasing, check the vocal range listed in the product details. A few digital vendors list the wrong key signature—that's happened to me twice with third-party sellers on Sheet Music Plus where the D major designation was wrong and the actual notation was in E flat. Cross-reference with the Hal Leonard catalog number if you can. If you're a performer looking to learn this on your own, getting the score with the full instrumental track from a licensed source beats using YouTube karaoke versions any day. The timing differences alone will throw off your practice. The official showtronics recording exists but is harder to find and often out of print now. One more thing about staging: this duet works best when the two singers aren't directly facing each other for the entire piece. The choreography usually calls for them to be apart during Hyde's opening section, then closing distance as Lucy enters. If you're mounting this for a small venue with limited staging options, having them simply stand two feet apart and shift their weight during the bridge works just as well as anything more elaborate. The emotional beat lands through phrasing, not blocking.
