Play a Rock Bass Line and Melody at the Same Time on Piano (Hand Independence)
To play a rock bass line and melody together on piano, learn an Em7 to A7 chord change with smooth inversions, learn a syncopated left-hand bass line on E F# G A B, add right-hand chords as whole notes, half notes and quarter notes, and then replace the chords with a melody while the bass keeps going.
Key points
- The progression is Em7 (E G B D) to A7 (A C# E G), using inversions such as B D E G and A C# E G for smooth changes.
- Find a flat seventh a tone below the root, and a major seventh a semitone below it, in any inversion.
- The left-hand bass line uses E F# G A B with syncopated notes on the 'and' counts.
- Add right-hand chords as whole notes, half notes, then quarter notes with dynamics before adding the melody.
- Sing the hard part, practise the bass most, and build the left hand up from a held E to the full line.
This lesson from Jason Zac at Nathaniel School of Music is for pianists who can already keep a steady left-hand pulse and want the next challenge: a real bass line in the left hand, the kind a bass guitarist plays in a rock, funk or blues band, while the right hand plays chords and then a melody. It suits confident beginners and intermediate players.
Step 1: Learn the two chords and their shapes
The progression is just two chords: E minor seventh (E G B D) and A dominant seventh (A C# E G). Beginners can use plain triads, E minor (E G B) and A major (A C# E), but use inversions so the hand barely moves:
- E G B to E A C#
- G B E (first inversion) to A C# E (root position)
- B E G (second inversion) to C# E A
Keep chords around middle C so you blend with a band and leave room for the singer. Test yourself by changing between two chords without looking, the way guitarists practise changes.
Finding the seventh in any inversion
Rather than always stacking the seventh on top of the triad, find the root inside whatever shape you are holding. The flat (minor) seventh is a tone, two chromatic steps, below the root: from E, that is D. A major seventh is just one semitone below the root: for A, that is G#. For A7 you want the flat seventh, G. The shapes used in the lesson are B D E G for Em7 and A C# E G for A7.
Step 2: Right-hand rhythms
Play the chords in three ways, counting 1 2 3 4:
- Semibreves (whole notes): one hit per bar.
- Minims (half notes): hits on beats 1 and 3.
- Crotchets (quarter notes): four hits per bar, with dynamics such as short, short, then a long or accented last hit, like a drummer opening the hi-hat at the end of the bar.
Step 3: The left-hand bass line
Place all five left-hand fingers over E F# G A B and get comfortable moving up and down those notes. The bass line uses only these five notes, with the beat divided in two: count 1 and 2 and 3 and 4 and. Many notes fall on the ands, which gives the groove its energy, and there is a short gap in the line. In the second bar, if landing on the and of 2 is too hard at first, play it on beat 3 instead. Sing the line as you play until it feels natural, then stop counting and think of it as a melody in the low register.
Step 4: Put the hands together
Add the right-hand chords as semibreves, then minims, then crotchets. Watch the chord change: the bass anticipates on the and of 4, but the right hand should not jump early with it. The hands naturally want to copy each other, so make one part almost automatic and watch the other consciously. Practise the harder part, the bass, the most. Once secure, vary the left hand between staccato and legato notes too.
Step 5: Add the melody
Jason's folk or Celtic-flavoured melody replaces the chords. Learn it in three small sections. For fingering, aim to get your middle finger on C# and your ring finger on D, with a finger cross where needed. An optional little triplet flourish adds a folk feel; skip it if it is tricky.
To combine melody and bass, build the left hand gradually:
- Hold E as a semibreve, then minims, then crotchets under the melody.
- Play a simple outline of the bass notes, then slowly sneak in the F#.
- Finally play the full bass line, pausing and holding a note to reset your mind if you get lost.
How to practise
Sing the part you are struggling with instead of playing it. Alternate sections of chords and melody over the bass. Think like a percussionist, and even tap the parts on your body away from the piano. Above all, treat it as music people can move to, not just an exercise.
Questions about this lesson
What chords are used in this rock bass line exercise?
Just two: E minor seventh (E G B D) and A dominant seventh (A C# E G). Beginners can use E minor and A major triads instead.
What notes does the left-hand bass line use?
It stays in a five-finger position on E F# G A B, with the beat divided into 1 and 2 and 3 and 4 and, and many notes landing on the ands.
Why does my right hand change chord too early?
The bass line anticipates the chord change on the and of 4, and the right hand tends to copy it. Make the bass almost automatic through repetition so the right hand can stay on the beat independently.
How can I make it easier to play the melody with the bass line?
Start by holding a single E in the left hand, then play it as half notes and quarter notes, then a simple outline of the bass, and only then the full line. Singing the left-hand part also helps.
