Where should I practice my trumpet？ピンチ、トランペットを吹く場所がない...

[My residence right next to Two train lines; Shinkansen & local one. no much noise from them. It is not possible for us to make noise with instruments in this packed place with 70 people sleeping, "Lord, give me a place for my trumpet or I will die as a musican]

March 14th, 2009 Where should I practice my trumpet? 

    “Lord, thanks for giving me a place to live but now I definitely need a place for me to have a practice of my trumpet everyday.”   While praying, a very kind friend of mine from Jesus Life House allowed me to use his 125cc-motor bike, then I found a bigger park 5 minutes away from my house. Praise the Lord! 

    I was kinda shy to start playing my trumpet even with a silencer but at the end of my stay, I made it well even before many of children playing around. “Ok, from time to time I will come here and do the same! Thank God.” 　

　　In my Church today they play jazz-oriented music; Hillsong which is so good, so I who used to play Classic & pop music except for jazz stuff am having hard time to adjust into it, so teach me, if you know how to get sense of jazz

「主よ。すべて必要なものを与えてくださってありがとうございます。でも今一度、願いを叶えてください。どこでトランペットを毎日練習すればいいのでしょう。トランペットは僕の単なる趣味でなく、もはや、あなたに対する礼拝なのです。僕のこころをラッパを通してあなたに捧げているのです。」

　今現在、ロックをベースにしている教会でトランペットを用いるには、僕がしてきたジャンル（クラッシック＆ポップス）違いです。でも今ジャズを独学で習っています。ちょいとむずいですね。このつかみ所のないこころの叫び・うめきを裏拍できりなく、表現しつづけることは。どなたかジャズをするコツを教えてくれませんか？

[だれもきませんように。May no one come and watch me playing my trumpet at a park]
