There are many questions about music basics, scales, keys, signs, harmony, chords etc. which could be answered by own researches if people had better strategies for searching.
This is because they don't know the terms like "music signs", "symbols", they don't only lack for theory but for music terminology. For this we have many posts like: "what does this letter or figure or that sign above that mean?"
That's why I wonder and ask: what are your best and most successful strategies to research about music information? (apart of asking in music theory and praxis)
