 Analysis of Nyanyi Sunyi has focused on the theme of God and His relationship to humanity , as well as of aspects of human existence : fate , dissatisfaction , and escape . Literary critics H.B. Jassin and Zuber Usman view the collection as an attempt to address Amir ’ s worldly problems . The collection has been noted as difficult to read owing to its usage of rarely used Malay and Javanese terms and basis in Islamic culture and Malay history . Despite this , Nyanyi Sunyi has been described as freer in its form than traditional Malay poetry , with what poet Chairil Anwar termed " compactly violent , sharp , and yet short " sentences which brought a new style to the Indonesian language .
