Hey Johnny, on page 37 of the ebook it shows the fingering for high F and F alternate but doesn’t show high F#. On video 3 of the fingering systems, C# to F#, the C# to high F is demonstrated and shows the small key on the side that new Saxophones have now days but doesn’t show how to hit a high F# if we don’t have that side key. Musically I know how important this is but didn’t know how to hit a high F#. Thanks!
