Steiner looked at the aspect of spirituality in music – and its expression in the instruments – from yet another angle. He claimed that musical instruments are created out of the world of imagination and have not been invented through 'trial and error' (Steiner 1980, p. 23). He thought that where musical instruments are sounding nowadays, spiritual beings used to be in the past (Steiner, 1980). Steiner compared the orchestra to the human organism (Steiner 1980), but excluded the piano from it, as he felt that it had been created rather from abstract ideas than out of spiritual imagination (ibid).
