How to Play Moonlight Sonata (1st Movement) on Piano
The Moonlight Sonata's first movement is slow, soft, and hypnotic — triplets rolling under a simple melody. This lesson covers the opening section: two long bass chords with the famous triplet pattern.
Because it is slow, this is a great piece for learning control and evenness. Start at 50% speed in Practice Mode.

✅ 4 Tips to Learn It Faster
- Keep the triplets perfectly even — use a metronome at a slow BPM.
- Play very softly (piano); the beauty is in the quiet, steady flow.
- Hold the long bass notes (C#, then B) for their full length.
- Don't rush the melody entry on G# — let it float over the triplets.
