The one thing I will take away most from this chapter is the importance of a solid technique in general.  Such as scales, arpeggios, trills, double notes and octaves.  We must master all of these to perfection in order to pass it along to our students as well as to improve our own musicianship.  I think Schumann addresses this when he recalls, "I looked at him with a smile, put Herz's finger-exercises before him, and told him to play one everyday for a week, and then come back and try the Concerto again.  This he did and called me his good genius, because my advice had helped him so much.  And he actually did the play the Concerto ten times better" (202).  This shows us that if we have a good solid technique and are continually going back to it in our practicing and incorporating it into our music, better music is produced. 

 Wieck was also a big fan of a solid technical approach.  We can see this from his daughter Clara when she writes in her diary expert about his frustration and her only being able to play scales, Cramer's etudes and Czerny's studies on the trill.  Wieck's own idea was one of taking the greatest care in the teaching  of technique and expression. (208)  

Also Brahms is the same way in his approch to instructing Eugeneie, Clara's daughter.  She states that he made her play a great deal of exercises, scales and arpeggios as a matter of course and also payed special attention to the thumb.  All in all I think Brahms really made her work on a lot of technique and not only in the exercises but also in the music that she played.  For instance in Bach he stressed rhythm the most.  But in the end all her hard work payed off and she saw the benefits of it.  "The seed which he sowed fell upon good soil and bore fruit in the course of years, and when I began to teach I recognized how much I owed to him" (225).  Therefore, a musician with a good solid technique will reap the benefits of it.  All these great musicians and composers of this chapter understood this and stressed the importance of it.  I think if we can follow their example and do the same with ourselves and the students we may have we will see a great improvement.
