This flute is in the key of D. It is tuned to the traditional Irish scale, the F# is flat, the A is sharp, the C# is flat, and the bottom D is also quite flat. We designate this tuning as "Traditional" tuning. If you're looking for a flute with standard tuning, please look for flutes labeled "Standard" tuning. No adjectives necessary, this is an ebony flute. It assembles in four parts and comes in a padded gig bag. At this price you can afford to get the best. The upper two sections have a brass slide for additional tuning. The center section slides into the top and bottom sections and has taped & thread wrapped ends for a secure fit. This flute is tunable. Assembled flute is 26 inches closed; slide opens the flute to a 28.25 inch length.
If you use fingering like a whistle, you'll find some notes of your Irish Flute sound "off." The traditional Irish flute is purposely tuned a bit flat. The F# is flat, the A is sharp, the C# is flat, and the bottom D is flat. Flautists believe these "off" notes came to the flute in the early 19th century. Explanations include: flutes were not originally played with "whistle" fingering; the "off" notes are a result of a 3-octave tempered scale; the "off" notes compensated for the flautist Charles Nicholson's method of blowing the bottom notes (G-D) more strongly than the A; and that the A and C# need to be slightly "off" in order to produce a good cross-fingered C-natural. Regardless of the reason, the traditional tuning for the Irish Flute is a bit flat.
Tuning a Flute with the Slide and Embouchure
Until you can produce good strong notes over the lower and upper octaves, don't worry about tuning. When you are ready, start by positioning the tuning slide so you produce a strong, full G at proper pitch. Beginners usually blow harder on the second octave causing it to sound sharp. With the flute, you don't blow harder to get the second octave; you adjust your embouchure by tipping your head up or down slightly, or by rolling the flute toward or away from you. Blowing down into the hole makes a note flatter, and blowing across the hole makes it sharper. Your tuning will improve, as your lip muscles strengthen and you develop a tighter embouchure.
Tuning a Flute with the Head End Cork
If the head-cork moves, your flute will get out of tune with itself (i.e., low notes not in tune with high notes). If this happens, use a 1/2-5/8" dowel apply steady, gentle pressure to move the cork. Keep the barrel section slid over the tuning slide so that you do not damage the slide. The cork is in the correct position when you are able to play both low B and high B in tune with each other.
