توصيف تصنيف الأنواع الموسيقية
أنشئ مهمة توصيف موسيقي مع تصوّر شكل الموجة ومعاينات مدتها 30 ثانية وتسميات أنواع هرمية.
Potato Team
يشغّل تصنيف الأنواع الموسيقية أنظمة التوصيات وإنشاء قوائم التشغيل واكتشاف الموسيقى. يوضح هذا الدرس كيفية بناء واجهات توصيف لوسم الأنواع مع معاينات صوتية وتصنيفات هرمية.

## Music Tagging Guidelines
### Genre selection
Choose one to three genres that describe the track. Prefer the most
specific genre that fits, and fall back to a broader one when unsure.
### Mood
Judge the overall emotional tone. A track can carry several moods.
### Energy and danceability
Energy is tempo, intensity, and power. Danceability is rhythm, beat
clarity, and groove. A slow track can be highly danceable.
### Listening
Listen to at least 30 seconds, and listen past the intro. Drops and
transitions are where the genre often becomes clear.

}نصائح لتوصيف الموسيقى
- سماعات عالية الجودة: ضرورية لدقائق الأنواع
- مستوى صوت ثابت: تجنب الإرهاق من التعديل المستمر
- معاينة كاملة: استمع بما يكفي لسماع التغييرات
- معرفة الأنواع: تعرّف على تعريفات الأنواع
- خذ استراحات: إرهاق الأذن يؤثر على الحكم
الخطوات التالية
- أضف كشف الأحداث الصوتية لتحديد الآلات
- أعدّ التعهيد الجماعي لوجهات نظر متنوعة
- تعرّف على مقاييس الاتفاق للموسيقى
التوثيق الكامل للصوت في التعليق التوضيحي للصوت.
