Where are the objects and the attributes in these sentences?
There was no reply, but in a moment Miss Glaser began to play the opening bars of one of Schumann’s songs. It was no strain on the voice, and I guessed that Miss Glaser knew what she was doing when she chose it. La Falterona began to sing, in an undertone, but as she heard the sounds come from her lips and found that they were clear and pure she let herself go.
I'm particularly interested in "in a moment", "of one of Schumann’s songs", "from her lips" and "no strain on the voice".
The attribute is a secondary part of the sentence which characterizes person or non-person expressed by the headword either qualitatively, quantitatively, or from the point of view of situation. http://5fan.ru/wievjob.php?id=47143 and http://5fan.ru/wievjob.php?id=46987
