A bass line refers to the progression of root notes played on an electric [bass guitar](https://www.masterclass.com/articles/guitar-101-what-is-a-bass-guitar-learn-about-different-types-of-bass-guitars-and-4-tips-for-playing-bass-guitar), double bass, cello, keyboard, or other bass instrument. A bassist will typically play the bass line in sync with the band's drummer. Bass lines play an integral role in rock music, electronic music, reggae, funk, hip-hop, pop, jazz, and R&B.

There are two main types of bass lines. 

- __Walking bass line__: Anchored around root notes in a chord progression, a walking bass line allows the player freedom in connecting those roots. Moving from one bass note to the next using scales or arpeggios, the bassist can make chord changes by "walking" from one chord to another. 
- __Bass run__: Also called a "bass solo" or "bass break," a bass run is an instrumental break in which all players stop playing except for the bass player. Bass runs are typically improvised bass riffs, although they may also be predetermined by the bassist.
A good bass line follows a chord progression, supports the guitarist, and syncs with the kick drum. If you want to experiment with writing your own bass lines, try the following tips.

1. __Know the root note__. Knowing the [root note](https://www.masterclass.com/articles/how-to-identify-the-root-of-a-chord) of each chord is the starting point for all great bass lines. The root note is the lowest note in the chord and works as the anchor for your bass line. For example, the G major triad is made up of the notes G, B, and D. G is the root note. 
2. __Choose your chords__. Choosing between [major chords](https://www.masterclass.com/articles/music-101-what-is-a-chord-learn-the-difference-between-major-chords-vs-minor-chords) and minor chords will determine the overall feel of the bass line. 
3. __Play notes in the same scale__. Playing notes within the [musical scale](https://www.masterclass.com/articles/the-basics-of-musical-scales) will help you maintain a cohesive sound. For example, if you're playing in the C major scale, you can play any notes within the scale.
4. __Play some notes off-beat__. If you know the [melody](https://www.masterclass.com/articles/music-101-what-is-melody) of the song, playing notes off-beat will help add harmonic depth to the song, allowing the melody to stand out.
5. __Add variation__. Try playing different notes, alternating between quarter notes or eighth notes for example. These rhythmic variations will add more percussive complexity to your bass riff.
