I would say my BFF Anista and I are like siblings. I would describe her as my sibling because we always argue like siblings sometimes but then after we get along and we are really close with each other and we talk almost every day that we can. We look out for each other like we are siblings. I love her so much and I appreciate her being there for me at my lowest times and making me happy.
Musical instruments of different types playing the same note may often be identified by the timbre of their sounds. Timbre is tone color, or tone quality which distinguishes different types of sound production.
