Locate the exact handoff
You can know every section and still hesitate between them. Find the last two bars of a verse and the first two bars of its chorus. Identify the final verse chord, the first chorus chord, and the beat on which the new harmony arrives. Check the recording for a pickup lyric or a held chord that crosses the boundary. Do not rely on the visual spacing between section labels to determine duration. Write a compact description in your notes, such as hold through four, then enter together on one.
Make the boundary your practice unit
Play only those four bars, keeping a spoken count through the handoff. Pause after the first chorus phrase and reset manually. If the transition remains uncertain, remove the strumming pattern or accompaniment figure and use sustained chords. Then restore the rhythm while preserving the same entrance. Practice once while watching the lyrics and once while looking briefly toward another musician. A transition should not depend on staring continuously at the screen. Pay particular attention to the chord before the change, since rushed preparation there often causes the apparent problem after it.
Connect the repaired joints
Repeat the method for the chorus into the next verse and for the bridge into the final chorus. Give each boundary its own cue rather than using the same vague instruction to get ready. Once the short units feel clear, play a full verse into a full chorus without stopping. Check whether your breathing, volume, or hand position changes before the boundary. Those preparations can help when intentional and distract when rushed. Finish by starting halfway through a section so you learn to navigate without the song's usual opening. Reliable joints let the larger arrangement feel continuous even when individual sections have different textures.
Count through instrumental gaps as carefully as sung phrases. A missing lyric removes one navigation cue, so use the number of bars and the next chord arrival to stay oriented through the silence.
