“The Haunted Mouse” is a Level 1 lesson piece in 4/4 time with a playful spooky character. The music uses simple rhythms, short repeated note patterns, long bass notes, slurs, ties, dynamic changes, and a final low-key sound effect. The piece is marked “Scampering along,” matching the image of a little mouse moving through a haunted house.

Measures 1–4 introduce the mouse character. The right hand plays short repeated notes and a small moving phrase, while the left hand holds longer bass notes underneath. The music begins softly and uses a long curved line across the phrase.

Measures 5–8 continue the same scampering style. The melody stays simple, with repeated notes and a descending phrase on “I hear people shriek!” The left hand continues to support the melody with long held notes.

Measures 9–12 bring a slightly stronger middle phrase. The lyric changes to “It’s a lot of fun to watch the people run,” and the music includes the instruction to grow louder.

Measures 13–16 form the closing section. The dynamic changes to forte, and the melody rises before settling into the final line. The piece ends softly with the instruction to play the lowest key on the piano, creating a spooky final effect.

Interesting fact: This piece uses both curved phrase markings and tied notes. The score includes a discovery activity asking students to identify each curved line as a slur or a tie.
