Composers of the period alternated florid and discant organum (more note-against-note, as opposed to the succession of many-note melismas against long-held notes found in the florid type), and created several new musical forms: clausulate, which were melismatic sections of organa extracted and fitted with new words and further musical elaboration: which was a song for more voices to be sung rhythmically, most likely in a procession of some sort; and trops, which were rearrangements of older chants with new words and sometimes new music. All of these genres save one were based upon chant: that is ,one of the voice,(usually three, though sometime four) nearly always the lowest sung a chant melody, though with freely composed note-lengths, over which the other voice sang organum.

这个时期作曲家的作品中华丽的奥尔加农和迪斯康特交替出现note-against-note(应该是自由奥尔加农，与由许多连续的装饰音组成的旋律对抗，这些装饰音对应在华丽部分中出现的长音，他们还开创了几个新的音乐形式：clausulae，来自于奥尔加农的拖腔片段，并配以新的词和更富悦耳的细节；conductus，孔杜克图斯，一种基于圣咏之上的有节奏性的单声或者多声歌曲，很有可能是用于礼拜的行列。

From the pleasant lilt of the penny whistle to the peaceful beauty of the Celtic Harp, Will Millar (I believe he was of the Irish Rovers) takes you to the green hills of Ireland with these stirring melodies and Celtic Whispers.

来自六音孔锡哨笛演奏的令人愉悦的轻松活泼的调子，去感受凯尔特竖琴声的宁静美丽，Will Millar用这些活跃的曲调和凯尔特私语开始将妳带到爱尔兰的青葱丘陵。

Second, it will help protect the inlays, purflings, and the rosette from color contamination due to the oils and dyes in the back and sides of the classical guitar.

其次，它会保护镶嵌，内饰线和音孔饰圈等不会相互染色，特别是来自背侧板的油脂和颜色。

After completing the sides of the guitar, apply a seal-coat coat to the rosette and the top purflings, re-folding the cloth to a new quarter each time.

完成侧板涂漆之后，给面板的音孔饰圈和内饰线也涂上漆，每次都折到干净的一面。

The tuning hand wheel is connected to spindle of drive bevel gear. The tuner joint is inside case. The worm wheel is fixed on stepped shaft fixed by nut. The worm engage to the worm wheel is fixed inside case. The upper end of worm is connected to the driven bevel gear. The spindle of drive bevel gear across the hole on the upper cover is connected to the hand wheel.

其特征在于：壳体上有一槽体，调音手轮与主动锥齿轮的轴相连接，调音器接头安装在壳体相应调孔内，蜗轮固定在调音器接头后端的阶梯轴上，用螺母固定，与蜗轮相啮合的蜗杆固定在壳体相应的孔内，用空心螺栓将其固定，蜗杆上端与从动锥齿轮连接，从动锥齿轮与壳体之间有垫片，主动锥齿轮的轴穿过壳体上盖的孔内，并且与手轮连接，用固定螺栓固定上盖。

On a regular 10-hole diatonic, or Marine Band type harmonica, the standard blues note bending technique involves an interaction between two reeds, one blow and one draw. On this style harmonica, only the higher pitched of the two notes from any given reed cell can be bent and then only to a point somewhat above that of the lower pitched reed.

在一般10孔口琴或者Marine Band类口琴上，标准布鲁斯压音是通过两个簧片(一个吸音簧片，一个吹音簧片)的协同振动实现的；所以只有两个音符中的高音符可以被压音，而且压音音符的音高也高于低音音符。
