Q: help! i think of a bunch of new musical ideas when im walking between things and dont have a good way to record it or write it down! how do i remember my ideas for later?
A: this is very important, because this is usually where a large percentage of your ideas come from, so it is important to have a technique for this. Use a voice memo app (most phones have them) and be quick and professional about how you frame it. establish where the root of the key is, establish where the time is, and correctly count it off, so there is no confusion about where the key and time are oriented. any hints about the groove or tempo are also very helpful, (perhaps compare it to another song's tempo, if that helps) and any other hints about how the idea is oriented in the song ('this is the top of of the chorus' or 'this would the the end title line of a chorus' or 'this would be a verse line' or any other hints you can think of). and if there are any specific chord things, mention that too, like if you know the whole thing starts on the 4 chord, or something like that. but most importantly remember to orient the key (sing a quick do re mi reference or something) and properly count off the time, and sing the thing, preferably a couple of times. overall your total demo + description should be about 15 to 20 seconds
