After composing the lyrics for a song, and a melody to go with the lyrics, the next important step is that of developing instrumental accompaniment for the song. That is the case, unless the song you have in mind is in the A Capella genre — in which case no instrumental accompaniment would be necessary.
Upon getting to that stage, where you have to develop instrumental accompaniment for your new song, you realize that you have two major options. The first option is that of using computer generated beats. And the second option is that of using live instruments.
There are pros and cons to each of those options. This is to say that there are pros and cons to the option of using computer generated beats. Similarly, there are pros and cons to the option of using the live instruments.
If you opt to use the computer generated beats, you will get to save money. This is the money — probably a considerable sum of it — that you’d otherwise have withdrawn and used to pay studio musicians (to play the instruments for you). This opportunity to save money is the upside here. On the downside, you may very easily end up with beats that lack the high level of authenticity associated with ‘real’ live instruments. Thus, the whole thing can be likened to the options you have for delivering a gift to a loved one. In that regard, you could opt to deliver the gift in person, or you could deliver it using a courier service such as UPS (whose operators refer to themselves as Upsers). And that is where you have to note that by opting to use such a courier service, you’d have the opportunity to access several advantages. The advantages in question include that of being able to track the progress of your gift parcel’s shipment using the UPS tracking functionality. But then, you also end up with a downside: in that this mode of parcel delivery lacks the ‘spontaneity’ (and hence ‘authenticity’) you’d otherwise have taken advantage of, had you opted to deliver the gift parcel in person. Opting to use computer-generated beats is the same.
On the other hand, if you opt to use the live instruments, you will probably end up with music that sounds more authentic (in my view) than anything you could possibly get from computer generated beats. But on the downside, having opted to use live instruments, you will have to contend with the payments for studio musicians who help you to play the instruments while recording. Going by my experience, the payments for the said studio artists can often turn out to be quite hefty. The studio artists are, after all, expert musicians who demand top-dollar payments.
