Bass Lines and Grooves
The laboratory offers 87 original general-purpose lines: 12 for each of 7 genres (jazz, soul/R&B, funk, fusion, blues, rock and Latin), plus 3 jazz walking lines. These are independently authored exercises. Grooves, melodic responses and fills differ in rhythm and note movement; fills last one bar and other lines four. Your phrase selection is restored when you return to the laboratory.
The bass laboratory collects grooves, fills, walking patterns and melodic lines. Instrument and study style guide register, articulation and movement.
- Choose a genre or study family.
- Select a line and set key, instrument and tempo.
- Identify roots, chord tones, passing notes and approaches.
- Listen to the connection between the end of one bar and the next.
- Send the phrase with DAW and compare it with the harmony track.
Walking and grooves have different roles
A walking line connects the harmony through continuous movement. A groove may instead rely on a recognisable rhythm, repeated notes or pronounced gaps. Choose for the arrangement’s needs, not simply the number of notes.
Chromatic approach notes depend on their destination. If you duplicate a line under different chords, check that its final note still leads to the intended root or voice. Renaming a block does not change its harmony.
Register and overlap
If the piano part contains very low bass notes, simplify it in its source or select a higher voicing. Volume balances parts but cannot by itself resolve two lines competing in the same register.
