round notes about the seventeenth century. Playford's well-known Whole Booke of Psalms, published about 1675, was probably one of the earliest books printed wholly with round notes.

28.—It follows from the foregoing rules that even so apparently simple a task as transcribing a part soprano, alto, tenor, or bass from a short-score hymn or chant book into a choir part-book is not mere copying. In the hymn or chant book the stems of one part are all turned the same way: in the part-book they must be turned according to their relation to the middle line.

Hooks.29.—With one exception, hooks should be made at the right-hand side of the stem; they are therefore sometimes at the same side as the note-head, and sometimes not.

30.—The exception is when longer and shorter notes are combined in the same group. In this case the hooks not common to the whole group are invariably turned so as to lie within the group, and, subject to this, if the group contains more than one beat, so as to lie within the beat of which they form part.
