1. What is a Piano Chord?

A piano chord is a harmonic set of three or more notes played simultaneously. The most basic chords are triads - three-note chords consisting of a root, third, and fifth interval.

2. How Chord Calculation Works

The calculator uses standard chord formulas:

\[ Major\ Chord = Root + 4\ semitones + 3\ semitones \] \[ Minor\ Chord = Root + 3\ semitones + 4\ semitones \]

Where:

Explanation: The formula builds chords by counting semitones (half-steps) from the root note on the piano keyboard.

3. Importance of Chord Theory

Details: Understanding chord construction is fundamental to music theory, composition, and improvisation. It helps musicians create harmonies and understand song structures.

4. Using the Calculator

Tips: Select a root note and chord type. The calculator will display the notes that make up the chord. All piano chords follow consistent interval patterns.

5. Frequently Asked Questions (FAQ)

Q1: What's the difference between major and minor chords?
A: Major chords sound bright and happy, while minor chords sound sad or melancholy. The difference is in the third interval (4 vs 3 semitones).

Q2: Why are some notes called sharp (#)?
A: Sharp notes are one semitone higher than their natural counterpart. On piano, these are the black keys between white keys.

Q3: Can I use this for guitar chords?
A: While the note names are the same, guitar chord fingerings are different due to the instrument's tuning and string layout.

Q4: What are extended chords?
A: Extended chords add notes beyond the basic triad, like sevenths, ninths, elevenths, or thirteenths.

Q5: How do I play these chords on piano?
A: Find the root note, then count up the keyboard to find the third and fifth. Play all three notes simultaneously.
