Not necessarily. Organs are not always bigger than tissues, they are just more complex. An organ can be as small as a lymph node, but a tissue may be as big as a muscle. So, the more complex it is, being made of more than one type of tissue classifies it as an organ, whereas the similarity of all the cells being the same categorizes it as a tissue. Organs are things like hearts, lung, livers, etc. Tissues are small/tiny pieces of animal or plants containing similar cells.
The first piano was a harpsichord. Then it was the organ, followed by the clavichord. Later, the piano was invented.
