A bass groove is the rhythmic and melodic foundation of a song — the repeating pattern that makes people tap their feet and move. It's the bridge between the drums (rhythm) and harmony (chords). A great bass groove locks in with the kick drum, creates momentum, and defines the feel of the track. In funk, the groove is the song; in rock, it drives the energy; in jazz, it provides the walking pulse that guides improvisation.

Funk: Heavy syncopation, 16th-note subdivisions, liberal use of space (rests), ghost notes, and slap/pop techniques. The "1" (downbeat) is sacred. Think Bootsy Collins or Larry Graham.
Rock: More straight-ahead eighth-note drive, root-5th patterns, consistent rhythmic pulse. Less syncopation, more power. Think John Paul Jones or Duff McKagan.
Jazz: Walking quarter-note lines with chromatic approaches, swing feel, connecting chord tones smoothly. Think Ray Brown or Paul Chambers.

The 5 rows represent scale degrees relative to your chosen key. From top to bottom: Octave (high root), 7th, 5th, 3rd, and Root (low). Funk uses b3 and b7 (bluesy), Rock uses natural 3 and b7, Jazz uses major 3 and major 7. Each lit cell shows which note plays at that 16th-note subdivision. Brighter cells = accented notes; dimmer cells = ghost/muted notes.

Swing (or shuffle) means that pairs of 16th notes are played unevenly — the first slightly longer, the second shorter — creating a "loping" triplet feel. It's essential for authentic jazz grooves and also used in blues, some rock (shuffle), and even certain funk styles. Toggle it on for instant jazz authenticity; leave it off for tight, straight funk and rock patterns.

This tool is perfect for:
• Rhythm training: Read the grid and play along with the audio to internalize different groove styles.
• Improvisation: Use the generated pattern as a backing idea and improvise variations over it.
• Transcription practice: Try to notate what you hear before looking at the grid.
• Songwriting: Generate a groove, record it, and build a song around it. The copy button lets you save patterns.

This version focuses on one-click generation with intelligent style-based algorithms. Each click of Generate produces a musically coherent, randomized pattern based on your style, key, complexity, and swing settings. For deeper customization, we recommend exporting/copying the pattern and loading it into your DAW or notation software.

You can choose any of the 12 root notes. The scale/mode adapts to the style: Funk uses a Dorian/blues hybrid (root, b3, 4, 5, b7); Rock uses Mixolydian (root, 3, 5, b7); Jazz uses Ionian/major with chromatic passing tones (root, 3, 5, 7). This ensures each groove sounds authentic to its genre right out of the box.
