I have been practicing sight singing very regularly using the movable do method. I am now attempting just to sing the notes without reference to any syllable such as do. Just taking a starting pitch from my pitch pipe and singing the notes la, la, la or da, da, da or what have you. It seems like the logical next step. I just want to put it out to the people who are more experienced than I to be sure I am not making a mistake in dispensing with the solemnization.
