In the recording album published by Diotima, he created 5 original compositions infused with ancient greek rhythms and traditional sounds, with the use of various percussive and wind instruments.
Composition started playing an important role for Kostas from the moment he could utilize percussion as a comprehensive set of performing orchestral music, by experimenting with the power of the natural complexion of percussive instruments and icorporating the classical form/style in works for percussion. He is using a wide variety of percussive instruments such as flower pots and mortars, that are producing clear and melodic sounds.
In 1997, he wrote music for the theatrical piece «Odyssey» that was presented in the Theater Festival of Thessaloniki and two years later he returned with an original composition for ballet and percussion called «Walk to the moon». In 2007 he created «Images for a percussive septet» that were presented by different percussion ensembles in Mylos Thessaloniki. For the department of percussion of the Contemporary Conservatory of Thessaloniki, Kostas has been composing works for small and large groups of students and he is transcripting several compositions for percussion use. In his latest album «Krousis kai Pnoes» he uses melodic and rhythmical percussion as his main instruments, in combination with wind instruments and choir. The album includes nine tracks, four of which were later on reworked to be performed by an orchestra in the form of a tetralogy. On the 2nd of June 2011, Kostas Hanis present his work «Krousis kai Pnoes» for percussion, wind instruments, choir and orchestra, together with the State Orchestra of Thessaloniki.
