2 snippets from the InPlainSight: A Stevie Wonder Tribute project. Both produced by Snapy Dee. Dem Dayz (I Wish) and No Need 2 Worry.
The song evolves around an 8 note bass line, which is repeated throughout the whole song (although the specific octave of the bass line does change). The key of the piece, like several other of Wonder's hits, is E♭ Minor, although the bridge of the piece is slightly different. The keyboard part consists of two chords during the chorus and verse: E-flat minor 7th (third inversion) and A-flat 7 (first inversion). Stevie Wonder also created a multi-layered monophonic synthesizer part which runs through the song's entirety. Throughout the chorus and verse, this varied Minor pentatonic scale (which can be played using just the black notes on a keyboard) is repeated and adds depth to the song. This piece has a syncopated horn section, as well.
In the TV series Classic Albums, Wonder recreated a small section from the song to demonstrate how he composed and arranged it. He played the keyboards and drums himself, and used most of the musicians that appeared on the original recording.

I think Stevie was 12 when he did this song.
