togjbo
togjbo, also nicknamed Poor Man's Toaq, is a non-serious proposal to turn Lojban into a tonal language. It has, in total, 6 tones:
- falling: à or a1
 - rising: á or a2
 - high: ā or a3
 - low: ȧ or a4
 - fall-rise/rise-fall: ǎ or a5
 - neutral tone: a
 
Tones can have both lexical and syntactic functions. Neutral is like a "default" tone. Any particle that isn't reassigned has a neutral tone.
There are five sentence starters:
| valsi | English | Equiv. | 
|---|---|---|
| .í | Yes/No Question | ixu | 
| .ì | Performative | ica'e | 
| .ī | Wish | i mi djaci lonu? | 
| .i | Assertion | iju'a | 
| .ǐ | Promise | inu'edo'u | 
| .ı | Warning | i.e'u | 
.ī is distinct from an imperative in that it's not a command, it's expressing desire that things should be like that.
.ī plíse fàrlu: I wish that the apple falls.
For brivla, this is how tones work:
| valsi | English | Equiv. | 
|---|---|---|
| á | Noun | lo X | 
| à | Verb | cu X | 
| ā | Tanru Continuuer | |
| ȧ | Preposition | fi'o X | 
| ǎ | Rafsi | ~ me la'e ra'oi X | 
| a | Part of the brivla | 
For brivla, any syllable except where the stress normally goes in regular Lojban gets the neutral tone.
If you want to use a brivla with another article than lo, make the brivla tone á anyway.
For noi/poi and be, you can specify the default slot by the tone.
| valsi | Equiv. | 
|---|---|
| a | X fa | 
| á | X fe | 
| à | X fi | 
| ā | X fo | 
| ȧ | X fu | 
| ǎ |
