D-flat on recorder is not easy to make as one has to partially uncover a hole.
So, to get the note D-flat we have to cover the 6 upper holes and the last one we will partially cover.
Look at this recorder fingering which explains perfectly how to play D-flat:
This will cause us to get the D flat because with just a slight lift of the finger we go from the note C to the note C sharp.
Remember that we also have to cover the back hole.
Well, I hope you’ve learned how to play D-flat on a recorder, this is the low note because there is a high D-flat on a recorder too, but we’ll study that one separately.
You can also see how it is written on the stave, keep in mind that D-flat is the same note as C-sharp, they are enharmonic sounds.
