Here's the rub....I don't understand and have so far in my playing had no need to understand - music or flutes which can be played chromatically, ITM, cross fingering, semi tone higher or lower, etc.
What I do understand is that with my Irish flute I can play pieces with 1 # or 2 #'s. If I bought a baroque flute which key signatures or type of music would the Eb key open me up to......or is it not that simple?
A keyless Irish flute in the key of D is based on the diatonic scale of D major: D E F# G A B C# D. These notes are obtained by closing all the holes (xxxxxx) and the lifting one finger at a time (xxxxxo for E, xxxxoo for F#, etc.).
A Baroque flute (traverso) will allow you to use
cross fingerings, such as xxxxox for F natural, xxoxxx for G#, etc. See for example
here. In addition, it has one key to play Eb, a note for which there is no cross-fingering available. With the help of the key and cross-fingerings, it is possible to play a full
chromatic scale, i.e. the 12 semi-tones of the scale, going up the scale one semi-tone at a time: D D# E F F# G G# A A# B C C# D
The Baroque flute plays and sounds quite different from the Irish flute. If what you are interested in is the Irish flute, you're probably looking for a
keyed Irish flute: 6 keys will allow you to play fully chromatically (with in-tune C's and C#'s) starting from low D. An 8 key flute will add two notes: low C# and low C.
On some flutes with large holes, it is possible to play some accidentals (notes which are not in the scale, e.g. Bb for D major) using half-holing. It's fine if you have a couple of accidentals here and there, but for anything serious you'll probably want a keyed Irish flute or a traverso.
Oh, and ITM = Irish Traditional Music
