I know this is a ridiculous question, but thought I'd ask anyways since I saw an article on wikihow for a low B. http://www.ehow.com/how_5210357_play-low-recorder.html I need a lower A than the one with 2 top holes(and the bottom hole) covered. It would allow me to play a lot of songs in the lower scale
The first question I would ask is which recorder are you playing on? The soprano and tenor recorders can go as low as C and the sopranino and alto recorders go down to low F. In the link you shared, I believe they are discussing an alto recorder. That being said, if you want to finger a low A on an alto recorder, cover the left hand holes as described in the link, then add the right hand index and middle fingers.
If you are ever confused about which type of recorder you are playing, the difference is mostly just in the size. The most common recorder is the Soprano. If you have a tuner or piano, you can check the key of the recorder (whether it is a C or F recorder) by playing the note that covers all the holes and see which pitch comes out.
