Overview

In this lesson, students will use the Circuit Playground’s buzzer feature to its full extent by producing sounds, notes, and songs. Students start with a short review of the buzzer's frequency and duration parameters, then move on to the concept of musical notes. Notes allow students to constrain themselves to frequencies that are used in Western music and provide a layer of abstraction that helps them to understand which frequencies might sound good together. Once students are able to play notes on the buzzer, they use arrays to hold and play sequences of notes, and compose simple songs.

New Code

• buzzer.note(note, duration)
• buzzer.playNotes(array, tempo)
• list.length
• var list = ["a","b","d"];
