Back in the 1990s, many years before mobile Internet access brought cultures of the world to the eyes and ears of America’s youth in the palm of their hands, it was media outlets like Nickelodeon which introduced a generation of kids to places and daily adventures outside of their own.

This was the same television network after all that introduced the children of the 90s to the sounds and styles of Gullah culture with Gullah Gullah Island, and brought nations together through sport and fitness with a teen-focused version of the Olympics with Global Guts–find me a kid who didn’t want to ascend that Super Aggro Crag.

In terms of music, however, there was no show on the loaded lineup of 90s Nickelodeon programming which had as strong of influence in turning a new generation of future music fans on to the colorful world of jazz like the smooth original score as heard in every episode of Hey Arnold!

The animated series which ran for 100 episodes over five seasons beginning in 1995 explored the rich diversity of pre-teen youths living in a fictional city very similar to that of a Brooklyn or uptown Manhattan. Urban life was a huge theme of Hey Arnold!, and considering the show’s setting was a creative twist on New York City, few musical genres have helped shape urban life (and vice versa) in NYC’s history than that of jazz, and this show was filled with it.

The person behind the show’s musical direction was composer Jim Lang, a former touring member of R&B vocal group the Pointer Sisters and Todd Rundgren collaborator. Lang’s efforts throughout the series undoubtedly set the framework for the smooth flow of each episode, which began with the lively spirit of the show’s recognizable theme song. The horn-filled, Bebop-inspired instrumental launched viewers into the quirky and fun world of the show and set the tone each week as to what viewers might experience with the animated exploration of city life.

“I remember, as we got onto the second or third series, thinking ‘I’m going to get as weird as I possibly can’,” Lang told Vice in a 2018 interview in relation to his experience working on the show. “‘I’m going to get some post-bebop Art Ensemble of Chicago weirdness into this.’ That was really fun – working with that freedom.”

The vibrant mix of lush, dreamy, and energizing jazz instrumentals heard throughout the series fueled extra life to the various adventures on which Arnold would embark alongside a colorful cast of friends, boarding-house roommates, neighbors, and eccentric grandparents. The smoothness of the instrumentals also helped to contrast some of the serious undertones which different episodes explored, and always found a way to compliment the scene without overtaking the dialog.

It wasn’t just the general introduction to jazz styles that made the show’s soundtrack such an enjoyable listening experience, but the diversity in emotions which Lang’s compositions evoked throughout each episode. Pieces like “Headin’ South” uses the melancholy tones of trumpets, atmospheric keyboards, and soft rhythms to establish more of a relaxed vibe, as if the characters had just wrapped a long, rainy evening about the city. In contrast, a piece like “Harold’s Boogie” lifted the viewers into the hustle and bustle of urban life, while keeping the mood light and soaring upward thanks to the bright and quirky lead lines from the xylophone and the spirited sounds of horns.

The piano and saxophone were also utilized by Lang to represent the innocent vulnerability of the show’s odd romance storyline between Helga Pataki and Arnold, as evident in tracks like “Helga’s True Love”. Also staying on the serious side, one of the more well-known episodes was that of the “Pigeon Man,” which featured a vagabond-like hermit character often found in cities across America. The theme to Pigeon Man does drift away from the traditional styles of jazz, but finds calming solace in soothing synths with some added strings and flute lines.
