Accordion:
- Single keyboard with buttons for both melody and accompaniment.
- The right-hand keyboard typically has two or three rows of buttons, each row producing different notes.
- The left-hand keyboard has buttons that control chords and bass notes, allowing the player to create accompaniment.
Piano Accordion:
- Piano-style keyboard on the right hand, similar to a piano keyboard, with individual keys for each note.
- The left-hand keyboard is similar to the accordion's, with buttons for chords and bass notes.
- The piano accordion's right-hand keyboard allows for more precise and nuanced melodies and harmonies compared to the button layout of a standard accordion.
Here's a table summarizing the key differences:
| Feature | Accordion | Piano Accordion |
|---|---|---|
| Keyboard Type | Single keyboard with buttons | Piano-style keyboard on the right hand |
| Right-Hand Layout | Two or three rows of buttons | Individual keys for each note |
| Left-Hand Layout | Buttons for chords and bass notes | Buttons for chords and bass notes |

Both the accordion and piano accordion are popular instruments known for their versatility and ability to produce rich, dynamic sounds. The choice between the two ultimately depends on the player's musical style, preferences, and technical skill level.
