I'm going through Larry Teal's daily studies for an alto saxophone (E-flat instrument). I'm practicing D sharp minor and I am seeing a B sharp and a C double sharp. Is B sharp a C? and the C double sharp a D? Please advise. Thanks

  • I think this question concerning minor melodic scales, leadt tone and enharmonic has been answered quit often else where. As the analysis and recognition in D# minor will be a a pretty hard thing I try to give you an answer. Hope you will understand it.. if not, you‘ll have to repeat the theory about minor scales and about the enharmonic signs. Jan 23, 2019 at 6:58

Short answer:

yes, it is!

If you transpose the piece of d# minor to the enharmonic eb minor, C double sharp will change to D and B# will change to C.

In this key you can better identify the two notes in question as the lead tone (D for C##) and C for B# as the natural 6th of the melodic minor scale.

The melodic minor scale is borrows the second tetrachord of the parallel major scale: the 6th and the 7th step are augmented:

Mi Fa So La -> Mi Fi Si La

D# melodic:

5, 6, 7, 8 -> A#, B#, C##, D#

Eb minor:

5, 6, 7, 8 -> Bb, C, D, Eb

as on the keyboard of the piano where you have to play for both scales the same keys it will be analog on the sax:

B# = C, C## = D


Yes, they are. A sharp raises a note by one semitone.

So, a B sharp is one semitone above B, so this is (broadly speaking) played as a C.

A C double sharp is two semitones above C, so this is correspondingly played as a D.
