Tango for double bass and piano

After many years, I have finally composed a new tango, my fifth so far. It is for double bass and piano, since my daughter Eva is a decent performer and always wanted me to compose for her. The tango has a typical A-B-A form and uses a modern musical language with added dissonances, based on a tonal centre of e but without clear major minor progress. The middle section is in much more clear yet still modal f sharp minor, very melodic and utilizes the high range of the double bass. The composition end with powerful energy and one final snap pizzicato on a low e.
