In practice
Because the pedal tone stays fixed while the chords around it shift, it creates a sense of grounded tension: some chords above it will feel stable against that held note, while others will feel more dissonant or restless, even though the pedal note itself never moves. This technique is especially common under a bridge or buildup, where the static bass note creates a feeling of suspended anticipation.
Arrangers often use a pedal tone to simplify a bass part while the chords above it do the harmonic work, which can also make a passage sound more open or ambiguous in key. Releasing the pedal tone and letting the bass finally move is a reliable way to signal that a held-back section is about to resolve.
Example
During a pre-chorus, the bass holds a single low D for eight bars while the chords above it move through D, G, and A, building tension that only releases when the bass finally shifts up to G at the start of the chorus.
