None but the Lonely Heart originates as a song and dates from 1869 coming from the composer’s Opus 6 collection. The poetry was written by the German romantic poet Goethe and subsequently translated into Russian. The music editor recommends reading a translation of the text although the clear message in the poem is an expression of loneliness. Although only 54 bars long the piece has great emotional and musical range making it an ideal assessment and audition piece. The repeating elements add unity to the song which has strong rhythmic and melodic shapes. Whilst there is a clearly evident phrase structure there are some overlapping phrases and the occasionally musical link which players need to take into consideration during a performance. Musically the falling minor 7th in the melody is characteristic as is the chromatic harmony which features a number of half-diminished 7th chords. Euphonium players should be aiming for a legato in their playing ensuring that they feature contrasting dynamics in a performance. There is a considerable amount of score detail and it is an excellent piece for developing control and quality of tone in solo playing. The suggested phrasing is determined by the shape of the melody and the punctuation of the poetry. Accompanists will need to make use of the sustaining pedal whilst the off-beat or syncopated chords in the accompaniment add to the intensity of the music. The realisation plays back at a tempo of 92 quarter notes or crotchet beats to the minute. There are accompaniments available playing at (1) 92 (2) 88 (3) 84 quarter note (crotchet) beats to the minute from the PlentyMusic website. A euphonium part notated in the treble clef and appropriately transposed is appended to the sheet music score.
