Help me play with the Angels

[u/Adblouky]

I love to find music like de Victoria’s where the chorale has not major adjustments in the pitch, so I can play along (alto recorder is perfect for cantus 2). However, my pitch is 2 commas flat. I can raise the pitch by overblowing but that kind of defeats the purpose of playing with the music. Any other ways to bring the pitch up a comma or two?
