It was originally Si, but it is better to use Ti instead, because then you can use only one letter to indicate each note: Do Re Mi Fa So La Ti. This is natural and nice not like the artificial ABC. And why do we need movable, Do is always the white key before the two blacks on piano While the sounds, Do Re Mi So La Fa Ti might seem like nonsense, they actually form a mnemonic device that has revolutionised the way we think about music. The scale's origins date back to 11th Century Italy and Guido of Arezzo, a music theorist, who modelled the scale on the "Hymn to St. John the Baptist". By the middle of the 19th century, the "fa so la" system of four syllables had acquired a major rival, namely the seven-syllable "do re mi" system. Thus, music compilers began to add three more shapes to their books to match the extra syllables. Numerous seven-shape notations were devised. He assigned the notes of the scale—C, D, E, F, G, A, B, C—a syllable: Do, Re, Mi, Fa, Sol, La, Ti, Do. Yes, it actually is sol: it's traditionally written that way when the tonic On a Fixed Do scale the A Note is assigned to La, the A was assigned because it has the precision of the frequency (440 Hz) which doesn't have decimals, so it's easier to remember. So you end up with a correspondence as follows. A = La B = Si C = Do D = Re E = Mi F = Fa G = Sol D = do; E = re F# = mi G = fa; A = sol; B = la; C# = ti; D = do; This can be applied to any major key (more on the common ones below). For minor keys, most people will make the starting pitch begin on la and move the same steps. For example, in the key of a minor: A = la; B = ti C = do; D = re; E = mi; F = fa; G = sol; A = la; Read more at our x5mkJX.

why do re mi fa so la ti
