I usually listen to bethoveen because when i hear it, it calms my nerves. The notes are soft, and the song is long enought for you to relax. My favorite song of Bethoveen is Fur Elise. I first experienced this when i played the piano when i was 8 years old. it influenced my mood enough to help me play his song entirely. Bethoveen song was originally played by piano, but over time, people added orchestra and violins. Hope this helps!
**Dopamine **production in the brain can be increased by listening to music. Anxiety and depression symptoms are lessened thanks to the enhanced dopamine production. The amygdala, a region of the brain involved in mood and emotions, directly processes music . Stress is lessened.
**Dopamine **is shown to be released into the brain when someone listens to music that gives them shivers, according to research. If you didn't know, dopamine is a type of joyful chemical that occurs naturally and is given to us as a reward in our reward system.
Blood flow to the parts of the brain that produce and regulate emotions is increased when you listen to (or create) music . When we hear music, the limbic system, which is involved in processing emotions and managing memory, "lights" up.

Jawab:Penjelasan dengan langkah-langkah:Volume pohon tersebut adalah sekitar 127.17 meter kubik. Perhitungan ini didasarkan pada asumsi bahwa batang pohon mendekati bentuk silinder dan menggunakan rumus volume silinder, dengan mempertimbangkan faktor bentuk.Berikut adalah langkah-langkah perhitungannya: 1. Konversi satuan:Tinggi pohon: 20 meter (sudah dalam satuan meter)Keliling batang pohon: 90 cm = 0.9 meter2. Hitung jari-jari (r) batang pohon:Keliling lingkaran (C) = 2 * π * rr = C / (2 * π)r = 0.9 meter / (2 * 3.14159)r ≈ 0.143 meter3. Hitung luas penampang batang (A):Luas lingkaran (A) = π * r²A ≈ 3.14159 * (0.143 meter)²A ≈ 0.0642 meter²4. Hitung volume batang pohon (V) tanpa faktor bentuk:Volume silinder (V) = Luas penampang * tinggiV = A * tinggiV ≈ 0.0642 meter² * 20 meterV ≈ 1.284 meter³5. Hitung volume pohon dengan faktor bentuk:Volume pohon = Volume silinder * faktor bentukVolume pohon ≈ 1.284 meter³ * 0.78Volume pohon ≈ 1.00152 meter³Catatan: Perhitungan ini adalah perkiraan karena bentuk pohon jarang sempurna silinder. Faktor bentuk digunakan untuk memperhitungkan perbedaan bentuk antara silinder ideal dan batang pohon nyata. Jika faktor bentuk tidak diberikan, biasanya digunakan nilai antara 0.7 hingga 0.8 untuk pohon kayu keras dan 0.6 hingga 0.7 untuk pohon kayu lunak , Neliti. Perlu diingat:Satuan yang digunakan harus konsisten. Dalam contoh ini, semua satuan dikonversi ke meter.Faktor bentuk dapat bervariasi tergantung pada jenis pohon dan kondisi pertumbuhannya. Pengukuran diameter pohon lebih umum digunakan untuk menghitung volume, karena lebih mudah diukur dan lebih akurat dibandingkan dengan keliling.
