reasoning ABC , these are the first 3 letters and they are iconic , and they are one of the names for the song (the ABC song) DEFG. when you sing the ABC song there is a pause between G and H. but DEFG don't fit in with the iconic ABC so DEFG is its own group HIJK . after the pause beetween G and H, but the HIJK is at normal speed . so they are are a group LMNOP . the fast part , when you sing the ABC song this part is the fast one. QRST . after that fast part these letters return to the normal speed, but they are pretty normal letters (with the exception of Q ) UVWXYZ . these are the freaky letters, some would argue that TUV is a section but T is too normal compared to U and V . and U and V can be with W since 2 V's make a W and W is called a W . WXYZ are freaky letters that are uses less often then other groups what inspired this filler project : https://www.youtube.com/shorts/yTzLHIoR4O4
