Music theory for piano: turn keys into connected harmony
Recognizing a chord symbol is one task; moving to the next chord smoothly is another. The keyboard makes harmony visible, but naming each voice helps you understand what actually changes.
Try the first exerciseThe working theory
Use inversions to reduce unnecessary movement
C–E–G is a C major triad in root position when C is the lowest note. E–G–C is first inversion, and G–C–E is second inversion. The notes still belong to C major; the bass note changes.
To move from C major to F major, compare C–E–G with C–F–A. C stays put, E rises to F, and G rises to A. This is one example of voice leading: following the motion of each chord voice.
Chord symbols and Roman numerals answer different questions. C names a particular chord; I describes the tonic chord in a major key. Thinking in both systems helps you transpose an idea without losing its function.
Your first experiment
Try it. Listen. Make one change.
- With a comfortable hand position, play C–E–G. Release tension between repetitions and name root, third and fifth.
- Move to C–F–A while keeping C as a common tone. Then try B–D–G for G major and return to C–E–G. Listen to each voice as it moves.
- Play the same sequence with single notes in the left hand: C, F, G, C. If two hands distract from listening, practice the voices separately first.
Check your understanding
Can you name the chord even when its root is not the lowest note in your right hand? Check the full set of notes before naming an inversion of the complete texture. For example, a left-hand C below E–G–C puts the complete C major chord in root position even though the right hand alone uses first inversion.
Take the idea into the laboratory
Piano Fundamentals introduces the instrument, Keyboard Fluency develops orientation, and the Triads, Inversions & Voicings Lab develops harmonic choices. ChordForge lets you build and hear progressions alongside that study.
Piano Fundamentals Lab
Learn the piano or keyboard itself: its repeating key layout, note-name geography, octaves, bench setup, finger numbering, key control, pedals, instrument controls, register, and safe practice setup.
Explore this Academy lab →Keyboard Geography & Fingering Fluency
Read the keyboard through landmarks, precise octave addresses and comfortable fingering, then navigate two independent hand routes without losing the pulse.
