Guido developed new techniques for teaching, such as staff notation and the use of the "ut–re–mi–fa–sol–la" (do–re–mi–fa–so–la) [[mnemonic]] ([[solmization]]). The syllables ut-re-mi-fa-sol-la (do-re-mi-fa-sol-la) are taken from the six half-lines of the first stanza of the hymn "[[Ut queant laxis]]", the notes of which are successively raised by one step, and the text of which is attributed to the Italian monk and scholar [[Paul the Deacon|Paulus Deacon]] (although the musical line either shares a common ancestor with the earlier setting of Horace's Ode to Phyllis (Odes 4.11) recorded in Montpellier manuscript H425, or may have been taken from there).<ref name="Stuart Lyons Do-Re-Mi">Stuart Lyons, ''Horace's Odes and the Mystery of Do-Re-Mi with Full Verse Translation of the Odes''.

"Ti" is used in [[tonic sol-fa]] and in the song "[[Do-Re-Mi]]".
