How to use chord construction on the staff
A root-position tertian chord builds alternate letter names above its root. Major and minor triads share a perfect fifth but use different thirds; a diminished or augmented triad changes the fifth. Seventh chords add another alternating letter. Choose the qualities to include in your session, then place all requested tones on the staff. The exercise checks the written note set, not just an unordered collection of piano-key pitch classes. It does not prescribe a hand position or fingering.
Try a concrete example
C4 major requires C4 E4 G4. C4 dominant seventh adds Bb4; B4 would create a major seventh chord. A-sharp has the same equal-tempered pitch as B-flat but is not the requested seventh spelling.
Make a small practice task
Build several major and minor triads first. Add one seventh quality only after you can explain its four chord tones.
Read the result carefully
Uses equal temperament and explicit written pitches. No account, teacher identity verification, secure exam proctoring or guarantee of learning. Local records and result receipts are editable by the device owner.
Work with the controls
- Choose treble or bass clef and written-note range
- Choose 1–50 questions and chord types
- Answer once, inspect the spelled-note explanation, then continue
- Keep optional local progress and XP
- Copy a repeatable configuration link; export a self-reported completion receipt
Use a short, repeatable task. Configuration links preserve the visible parameters and start a fresh session rather than sharing private scores. In an exercise, submit one first answer, inspect the revealed spelling and choose Next question. A completed set offers a self-reported receipt. Diagram exports and achievement summaries have their own controls above; they do not evaluate an acoustic performance.
Use the connected resources below to move from this experiment to a specific chord, scale or listening task. A diagram identifies pitches; a generated example gives you something to inspect and adapt. Neither is a prescribed fingering or an assessment of your physical technique.
