Different Left Hand Accompaniments

Exploring Left-Hand 8 Accompaniments in Piano Music

One of the joys of playing the piano is discovering how much variety exists in the left hand’s role. Far from being just “background,” left-hand accompaniments give music its rhythmic drive, harmonic support, and emotional color. Whether you’re accompanying yourself while singing, playing a classical piece, or experimenting with jazz, your left hand shapes the sound just as much as your right.

Let’s explore eight of the most common and effective left-hand accompaniment styles.

1. Alberti Bass

A hallmark of Classical-era piano music, Alberti bass breaks up chords into a repeating pattern: low-high-middle-high. It creates a flowing, harp-like texture that was beloved by Mozart and his contemporaries.

• When to use: Classical sonatinas, lyrical melodies that need gentle motion.

• Sound quality: Light, elegant, and balanced.

While I personally don’t use Alberti Bass in the strictest sense in my own piano music I do it in a freer more atmospheric way. A strict Albert Bass example would be Mozart’s Piano Sonata K 545. 

2. Waltz Bass (Oom-Pah-Pah)

In waltz time (3/4), the left hand often plays a bass note on the first beat and chords on beats two and three. This gives the music its lilting, dance-like character.

• When to use: Waltzes, folk-inspired pieces, or anytime you want a swaying motion.

• Sound quality: Buoyant, rhythmic, and charming.

I do a variation of this in my own music including songs ‘Gypsy’ and ‘Haunted Past’ However an example of this in the truest sense can be found in the song ‘The Blue Danube’ by Johann Strauss. 

3. March Bass (Oom-Pah)

Similar to the waltz bass, but in duple meter (2/4, 4/4). The left hand alternates between a low bass note and a chord, often producing a strong, march-like rhythm.

• When to use: Polkas, marches, lively folk tunes.

• Sound quality: Bold, driving, and energetic.

A great example of this is ‘Turkish March’ by Mozart. 

4. Broken Chords / Arpeggios

Instead of playing chords all at once, the left hand can “break” them into rolling arpeggios, either ascending, descending, or spanning multiple octaves. This adds fluidity and richness.

• When to use: Romantic-era pieces, ballads, or anytime you want a flowing accompaniment.

• Sound quality: Expansive, lush, and shimmering.

This is where my songs shine and the left hand style I use the most. Numerous songs of my own use arpeggios. Great example is ‘Dark Night of the Soul’ 

5. Stride Bass

Popular in early jazz and ragtime, stride bass alternates between a low bass note (often the root or fifth) and a chord played higher up. The wide leaps give this style its distinctive bounce.

• When to use: Ragtime, swing, stride piano styles.

• Sound quality: Playful, rhythmic, and full-bodied.

This one is really fun, usually in 4/4 time a great example is ‘Carolina Shout’ by James P Johnson. 

6.  Walking Bass

Borrowed from jazz, a walking bass line moves stepwise or in intervals through the chord tones, creating a steady “walking” motion. It’s a melodic accompaniment that doubles as harmonic support.

• When to use: Jazz standards, blues progressions, swing pieces.

• Sound quality: Smooth, grooving, and melodic.

Think ‘The Pink Panther Theme’ by Henry Mancini. 

7. Ostinato Patterns

An ostinato is a repeating rhythmic or melodic figure. In the left hand, this can anchor a piece with hypnotic stability while the right hand explores freer melodies.

• When to use: Minimalist music, dramatic builds, or to create tension.

• Sound quality: Mesmerizing, rhythmic, and atmospheric.

I’ve used this technique in my own music including ‘Racing Against the Sunset’ Other examples include ‘Bolero’ by Ravel, or ‘Canon in D’ by Pachelbel. 

8. Open Fifths and Octaves

Sometimes simplicity speaks loudest. Playing just the root and fifth (or doubling in octaves) strips harmony to its essentials, giving a bold, grounded sound. This is especially common in folk, pop, and cinematic music.

• When to use: When you want strength without harmonic complexity.

• Sound quality: Strong, open, and primal.

A good example of this is in my arrangements of ‘America the Beautiful’ or the opening chords of ‘Angels We Have Heard on High’ or ‘Auld Lang Syne’ 

Bringing It All Together

Mastering these accompaniment styles gives you flexibility as a pianist. By choosing the right left-hand pattern for the right context, you can instantly change the character of a piece—from delicate elegance to bold drive. Try experimenting: play the same melody with Alberti bass, then with stride bass, and notice how the mood shifts.
