A practical checklist for preparing a shared sing-along screen, using an illustrative rehearsal rather than claims of completed tests. I am associated with Karaoke Maker, and AI assisted these notes. Use authorized music and lyrics; manual editing has a free path, while automatic processing uses credits. Check current terms.

## Items

### 1. [Identify the room and viewing distance](https://listium.com/@mathaichat/151620/five-checks-for-a-shared-sing-along-screen/0/identify-the-room-and-viewing-distance)

Item ID: `0`

- Notes: Write down the intended screen, approximate viewing distance and lighting before choosing a layout. A television, projector and laptop can impose different constraints. If the real room is not available yet, label that uncertainty and plan a later check on the actual equipment. Try the longest phrase at the expected scale and note any edge cropping. This is a proposed checklist, not a claim that a particular venue has already been tested.

### 2. [Confirm rights and source versions](https://listium.com/@mathaichat/151620/five-checks-for-a-shared-sing-along-screen/1/confirm-rights-and-source-versions)

Item ID: `1`

- Notes: Identify the exact audio recording and the authorized lyric text before editing. Different arrangements can have different introductions, repeats and breaks, so timestamps from one version may not fit another. Record the source and any unresolved permissions in a short handoff. A browser editor does not grant rights to distribute music, words or artwork; confirm the intended use before sharing beyond the editing team.

### 3. [Check phrase timing and lead-in](https://listium.com/@mathaichat/151620/five-checks-for-a-shared-sing-along-screen/2/check-phrase-timing-and-lead-in)

Item ID: `2`

- Notes: Mark the musical sections and review when each phrase appears, when singing begins and when the emphasis moves on. The next line should be visible early enough for a first-time reader without hiding the active line. Check a fast phrase, a sustained word and a long instrumental pause at normal playback speed. Describe specific timestamps and observations rather than claiming that one timing interval fits everyone.

### 4. [Review contrast and active cues](https://listium.com/@mathaichat/151620/five-checks-for-a-shared-sing-along-screen/3/review-contrast-and-active-cues)

Item ID: `3`

- Notes: Inspect the longest line at its actual display size and check the weakest background contrast, including moving highlights or images. Leave room around the edges where a player or screen might crop the video. If active words change color, consider an additional shape or weight cue so color is not the only distinction. Avoid distracting flashing; check both a paused frame and continuous playback.

### 5. [Verify export and handoff](https://listium.com/@mathaichat/151620/five-checks-for-a-shared-sing-along-screen/4/verify-export-and-handoff)

Item ID: `4`

- Notes: Open the actual exported file in an appropriate player and inspect the beginning, middle, end and an instrumental break for missing words, cropping or drift. Use one clearly labeled revision and keep an editable copy. Record which device was checked and any outstanding limitations; do not claim a venue test that has not occurred. Provide a permitted local copy and a simple fallback if the host expects unreliable connectivity.
