Part 2. What is a Bassline in Music?

A bassline is the low-pitched part of a song that gives the track its foundation. It shapes the harmony, sets the rhythm, and adds the groove that makes music feel alive.

Basslines are often played on instruments like electric bass, double bass, or synths. Acting as the bridge between rhythm and melody, they make a song feel complete and balanced.

Key Features

⭐ Harmony Foundation – Follows the chord roots and gives the song structure.

⭐ Rhythmic Anchor – Locks in with the drums to keep the beat steady.

⭐ Groove Setter – Defines the "feel" of genres like funk, jazz, and EDM.

⭐ Musical Bridge – Connects percussion with melodic instruments.

Examples of Bass Lines

• "Billie Jean" by Michael Jackson: The instantly recognisable bass groove drives the whole track.
• "Another One Bites the Dust" by Queen: That iconic groove takes the lead.
• "Seven Nation Army" by The White Stripes: A modern anthem built around its unforgettable bassline.
