Program note


for accordion solo

The score is in exact pitch, and the proposed registers can be changed according to room and instrument etc. The three pieces can be performed individually or as a suite.

Momentum is dedicated to Bjarke Mogensen and is in three movements:

Momentum I – 4-5 min Moderato più mosso
Relative slow and minimalistic movement based on a long sequence of major thirds.
Momentum II – 3 min Allegro con brio, Moderato nòbile con brio
Fast movement based on a melody heard in it's pure form in the middle of the pieces
Momentum III - 4 min Moderato, Andante più mosso
Relative slow movement based on a melody which is heard in pure form in the end of the piece.

A musical technique where different layers of music in individual tempos, metric and musical style are combined in a simple pattern of chords, which slowly modulate through all the keys in a newer ending sequence, creating a music with no or very few dissonances.

I've developed the technique by combining different musical methods used in older works.

  1. Use of multiple layers of music, which have been a important part of my music since 2000.
  2. A simple repeating sequence of chords as the only harmonic material in the piece, which creates a music on the move, in a never ending modulation from the start to the end. Used in works like Haiku (1999), In liquid... (violin and piano) (2003) and Image balancantes (2004).
  3. A 'rhythm across harmony' principle, where different together sounding motives are played in individual tempos across the rhythm of the chords.

First used in Smoke (2000) and developed as a technique in Liebestraum (Liszt arrangement from 2005), and later used in 8 momenti mobile (2008) before it finally evolved to the technique used in Concerto in tempi from 2010 and forward.

Martin Lohse 2014


for akkordion solo

En teknik hvor forskellige lag af musik i hver deres tempo, metrik og musikalsk stil kombineres i et simpelt mønster af akkorder, som langsomt modulere igennem alle tonearter i en uendelig sekvens, skabende en musik med ingen eller ganske få dissonanser.
