This is my practice on Sandbox


 * 1) Sources added for Janissary
 * 2) "One corner of the triangle is left open to keep the instrument from having a specific pitch and to allow it to generate ethereal, scintillating overtones instead"  http://www.philharmonia.co.uk/explore/instruments   This explained the hole on the triangle better that what was written.
 * 3) I added an "ancient and medieval period" paragraph since I found more appearances of the triangle before Janissary Bands
 * 4) I deleted "it was first made in 16th century in England" since there is no source to support it.
 * 5) I added a section of manufacturing to go together with shaping
 * 6) * Hotchocolatchland 6. I added two periods in the history section.  7. Added two citations, one from a book, one from a website.  8. Deleted one sentence that has no source.  9. Corrected some format errors.
