{ start: 24, duration: 4, text: "Let's practice the downstroke technique. Start slowly and build up speed." },
{ start: 28, duration: 6, text: "Try strumming the open strings. Listen to the sound - it should be clear and even." },

{ start: 63, duration: 5, text: "If any notes sound muted, adjust your finger pressure and position." },
{ start: 68, duration: 4, text: "Common mistake: letting your thumb wrap around the neck. Keep it behind." },
{ start: 72, duration: 6, text: "Practice switching between open strings and the G chord. Do this slowly at first." },
