For decades, children have been taught the song as 'A-B-C-D-E-F-G, H-I-J-K, L-M-N-O-P, Q-R-S, T-U-V, W-X, Y and Z, Now I know my ABCs, Next time won't you sing with me?'

But now, Rachel Sorsel, an educator specializing in structured literacy, literacy intervention and dyslexia who has taught hundreds of students in the past five years, reveals that there is a new way to sing the chant - and for good reason. 

Young kids are now singing: 'A-B-C-D-E-F-G, H-I-J-K-L-M-N, O-P-Q, R-S-T, U-V-W, X-Y-Z, Now I never will forget, how to say the alphabet.'

The alteration comes after hundreds of years of The ABC Song, which was created in 1835, set to the tune originally composed by Wolfgang Amadeus Mozart in 1761.

In a now viral video, Sorsel explained that instructors have changed the classic 'LMNOP' and 'Y and Z' groups after children kept signing the former as 'ellemenopee' in one breath and would assume that the 'and' in 'Y and Z' was an actual letter. 

'I'm a teacher and I don't teach the alphabet like the way I grew up singing it.

'And this is one of the reasons because kids hear "LMNOP" and they don't say the individual letter names. Some even think this is one letter. 

'Another reason is because at the end of the traditional alphabet song, we sing Y "N" Z and some kids think that YN is a letter or NZ is a letter.'

But while the change is for good reason, many have been left wondering why a new era of children are unable to understand the classic version of the song.
