We will also play Little Red Fox. Use this to practice playing chords by reading the I, IV, V. In fact, try changing keys.
Also start working on your Bb chord exercises on page 14. Play the notes in the exercises using the chord shape. Remember to take breaks and don't press too hard, and play a partial chords when you can.
Start working on the notes for the Uke I of Barney and Katy. This is a really cute little jig. Focus on finger efficiency. For example, keep your 1st finger down in Measures 1 to 4 while reaching up to play the other notes.
