Editors 'Note: In reply to a letter from Sol Babitz in the November 5 issue of the NYR ” in which, owing to an editorial slip, the word "mordent" was misspelled ” Stanley Kauffmann writes:
But most importantly, it acts as a mordent, making the color permanent and a little shiny.
Dum contumelia vacant et festiva lenitate mordent, mediocres animi aegritudines sanari solent, &c. 3498.
The American College Dictionary defines a pralltriller as "an inverted mordent."
A New Dictionary of Music by Arthur Jacobs says: "These two [ornaments] are sometimes called respectively inverted mordent and just mordent; and in German Mordent means only the second, the first being called Pralltriller."
In the case of both mordent and double-mordent the tones are sounded as quickly as possible, the time taken by the embellishment being subtracted from the value of the principal note as printed.
When the sign ([turn symbol] or [fancy turn symbol]) occurs over a note of small value in rapid tempo (Fig. 45) the turn consists of four tones of equal value; but if it occurs over a note of greater value, or in a slow tempo, the tones are usually played quickly (like the mordent), and the fourth tone is then held until the time-value of the note has expired.
The _mordent_ [mordent symbol] consists of three tones; first the one represented by the printed note; second the one next below it in the diatonic scale; third the one represented by the printed note again.
The _inverted mordent_ [inverted mordent symbol] (note the absence of the vertical line) is like the mordent except that the tone below is replaced by the tone above in each case.
The _double (or long) mordent_ has five tones (sometimes seven) instead of three, the first two of the three tones of the regular mordent being repeated once or more.
