None but the Lonely Heart originates as a song dating from 1869 and comes from the composer’s Opus 6 collection. This arrangement for flute accompanied by marimba and acoustic guitar keeps close to the composer’s original version of the song and is an excellent piece for the flute player to develop both control and quality of tone in their playing. The accompaniment comprising marimba and acoustic guitar with off-beat or syncopated chords adds both intensity and urgency to the music. The suggested phrasing is determined by the shape of the melody and the punctuation of the poetry. The realisation plays back at a tempo of 90 quarter notes or crotchet beats to the minute. Individual parts are appended to the full sheet music score and the marimba and acoustic guitar accompaniment is available playing at (1) 88 (2) 90 (3) 92 quarter note (crotchet) beats to the minute as an mp3 download. For a piece of just 54 bars in length there is a considerable musical and emotional range in the music with the music editor suggesting that this is both an excellent performance and assessment piece.
