For *An enharmonic change is a change to the eye but not to the ear. example, the keys of F (signature six sharps) and of Gb (signature six flats), though they appear differently on the staff, are the same to the ear when played upon the pianoforte or other instrument. Rule: In regular transposition by flats, 4 in the scale of one key is taken as I (the key tone) in the succeeding key. These exercises in transposition should be sung both with and without help from an instrument. After singing, compare the last tone with the first tone to ascertain how much the pitch has been changed. |
