Problem: Given the question: Extract the answer to the question from the following context. Question: What type of sheet music was made? Context: As the economy and the middle class expanded, there was an increasing number of amateur musicians. One manifestation of this involved women, who became more involved with music on a social level. Women were already engaged in professional roles as singers, and increased their presence in the amateur performers' scene, especially with keyboard music. Music publishers begin to print music that amateurs could understand and play. The majority of the works that were published were for keyboard, voice and keyboard, and chamber ensemble. After these initial genres were popularized, from the mid-century on, amateur groups sang choral music, which then became a new trend for publishers to capitalize on. The increasing study of the fine arts, as well as access to amateur-friendly published works, led to more people becoming interested in reading and discussing music. Music magazines, reviews, and critical works which suited amateurs as well as connoisseurs began to surface.

Please answer this: Extract the answer to the question from the following context. Question: hydrogen is highly soluble in Context: Hydrogen is highly soluble in many rare earth and transition metals and is soluble in both nanocrystalline and amorphous metals. Hydrogen solubility in metals is influenced by local distortions or impurities in the crystal lattice. These properties may be useful when hydrogen is purified by passage through hot palladium disks, but the gas's high solubility is a metallurgical problem, contributing to the embrittlement of many metals, complicating the design of pipelines and storage tanks.
