Thai Dead Syllables

The new piece waiting for you in Week 2 is dead syllables, and the rule is smaller than the full tone chart makes it look. When a syllable ends in a stop final like -k, -t, or -p and has no tone mark, most of them simply land on low tone.

A quiet morning desk with an open notebook, plain study cards, and coffee by a window — For the first quiet minutes of the morning.

I checked this against Thailand Starter Kit's live and dead table and a second source, and they agree on the shape of it. For a mid or high class initial, a dead syllable is low whether its vowel is short or long, so จาก, with a mid class จ and a final -k, reads "jaak" on a low tone and means "from."

The one place length actually changes the tone is with a low class initial. You can hear the whole split in a pair worth carrying into a morning session: มัก and มาก share the same low class ม and the same final -k, and only the vowel length moves. มัก, with the short vowel, reads "mak" on a high tone and means "often," while มาก, with the long vowel, reads "maak" on a falling tone and means "a lot."

So the order I would use is plain: spot the stop final and call the syllable dead first, then check the class. If it is low class, check the vowel length, and if it is not, you are already done at low tone. That is a morning-sized piece ahead of today's Week 2 pack, and I will be curious whether the pack sequences it the same way when it lands.
