At f, diu-iiig the liold ^tn upon the pedal, the Great Organ reed is shut off, other stopsadded if necessary, the Great to Pedal Coupler drawn, and the aceonipauinient of the voicesbegins. This form of giving out the tuneâin the Tenor rangeârequires some care inconsequence of the inversions of the harmony which ai-ise. Experienced liannonists will at onceperceive that by this process a sequence of fourths (allowed in composition) becomes, byinversion, a sequence of fifths, which is justly forbidden. For the benefit of those to whomthis may not be clear an illustration follows. Example 54. (Melody m Soprano:Higher than Accompaniment.) -t^w a-teE=|± i Example 55. (Melody in Tenoe: AcCOMPAiaMENT ABOVE.). At the asterisks (**), Example 54, the sequence of fourths will be noticed occurringbetween the Alto and Soprano. In Example 55, these foiuths have, by inversion, become fifthsoccurring between Tenor and Soprano. A possible correction of Example 55, by beginning with the third of the chord as thehighest note of the accompaniment, and thus restoring the sequence of fourths, would be thef oUowino;: Inversion, when to be avoided. Example 56. aâIâ- --£. -2-â*- im l^ 2?- HTSzir: 9^1 m ^^ The effect of this is rather artificial, and where aprolonged sequence occurs it Avill generally be ad\isablenot to attempt its inversion. Where the inversion willonly produce an occasional fifth progressionânot asequence of themâit will be found easy to avoid thesame. This form is also particula
