• Chord Notes and Inversions
  Look up piano chord notes and inversion shapes on a labeled keyboard. Use the page as a reference while practicing; it is not a lesson sequence.
• Scale Reference
  View scale notes and patterns on a keyboard diagram to identify their key positions.
• Labeled Keyboard Diagrams
  Use labeled 88-key and 61-key example layouts, with optional octave labels, to locate note names.
• Note Frequency Reference
  Look up piano note names, MIDI numbers, and calculated equal-tempered frequencies from A0 through C8.
• Printable Practice Resources
  Open a C4–C5 key-name worksheet and answer page, or download blank staff paper for writing practice.
