"Happy Gnomes" is The Synthesatsers' delightful detour into a more playful and quirky side of electronic music. The track begins with twinkling synths and a melody that bounces along with the joyous innocence of a children's tune. It’s easy to imagine the song serving as a soundtrack to a mythical world, full of wonder and miniaturized adventure. The song structure is buoyant, featuring a jaunty rhythm that skips and hops like the fantastical creatures it's named after. There's a prominent use of bell-like synth tones that mimic the sound of a xylophone, adding to the enchanting, fanciful vibe. A bouncy bassline underpins the melody, giving the song a danceable groove despite its lighthearted, almost mischievous melody.
